# Remote MCP Endpoint

> **Remote MCP endpoint:** `https://misakanet.org/mcp`
> **Transport:** Streamable HTTP
> **Auth:** Bearer token for read tools; anonymous, rate-limited intake for `misakanet_submit_intake`
> **Protocol:** MCP 2025-06-18 (forward-compatible with 2026-07-28 RC)

MisakaNet exposes a Streamable HTTP MCP endpoint at `https://misakanet.org/mcp`. Any MCP-compatible client can connect remotely without cloning the repo.

For the crawler/agent-oriented flow, see the [HTTP MCP journey](../journey/http-mcp/).

The server also supports local stdio transport as an alternative (see [Local stdio](#local-stdio-alternative) below).

## Intake Ways: Submit Lessons Without GitHub Account

MisakaNet provides **3 ways** to contribute lessons, from anonymous to fully registered:

### Way 1: Anonymous Intake (No Account Required)

Use this when an agent searched MisakaNet and found no good lesson. This path does **not** require GitHub, email, a browser, or a Bearer token. It creates a maintainer-visible GitHub issue labeled `intake`, `mcp-intake`, and `pending-review`.

**When to use:**
- Agent hits an error not documented in MisakaNet
- Existing lesson is stale or incorrect
- Quick failure report for maintainer review

**Important:** Anonymous access is not a loophole around `initialize`. `initialize`, `tools/list`, `server/discover` and the read tools (`misakanet_search`, `misakanet_get_lesson`) are all reachable with no token; what anonymous callers get is a **burst window** of 20 reads per 60 seconds per address (`READ_BURST_LIMIT` / `READ_BURST_WINDOW_SECONDS` in the worker) — a speed limit, not a daily quota. Registering lifts it. For no-account intake, call `tools/call` with `misakanet_submit_intake` directly — it is anonymous too, and is protected by intake-specific guards rather than by auth.

```bash
curl -sS https://misakanet.org/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -H "Origin: https://claude.ai" \
  -H "User-Agent: MisakaNet-Remote-Agent/1.0" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_submit_intake","arguments":{"kind":"missing_lesson","problem":"SHORT REDACTED PROBLEM","error":"OPTIONAL REDACTED ERROR","what_tried":"OPTIONAL","fix":"OPTIONAL","verification":"OPTIONAL","matched_lesson_id":"","source":"remote-agent"}}}'
```

**Questions vs failures:** `kind="missing_lesson"` is for failure reports. For a how-to / knowledge question, set `kind="question"` — the issue opens as `[Question]` with a `needs-answer` label and is **not** scored/archived as a lesson. Its exit is an answer posted in the thread (a maintainer labels it `answered`, and `sync-question-answers.yml` copies it into the FAQ) — not a pull request, and not a human review of each item. Questions left the `needs-human-review` queue on 2026-10-17: that label meant "a person must read this one", and 153 intake issues carried it. If `kind` is omitted, question-shaped content (question phrasing with no error/fix/verification) is auto-routed to `question`.

### Python snippet (direct `tools/call`)

Anonymous crawlers and scripts can call `misakanet_submit_intake` directly using `urllib` or `requests` by supplying explicit headers:

```python
import json
import urllib.request

payload = {
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
        "name": "misakanet_submit_intake",
        "arguments": {
            "kind": "missing_lesson",
            "problem": "SHORT REDACTED PROBLEM",
            "error": "OPTIONAL REDACTED ERROR",
            "what_tried": "OPTIONAL WHAT WAS TRIED",
            "fix": "OPTIONAL RECOMMENDED FIX",
            "verification": "OPTIONAL VERIFICATION STEPS",
            "matched_lesson_id": "",
            "source": "crawler-python",
        },
    },
}

data = json.dumps(payload).encode("utf-8")
req = urllib.request.Request(
    "https://misakanet.org/mcp",
    data=data,
    headers={
        "Content-Type": "application/json",
        "Accept": "application/json",
        "Origin": "https://claude.ai",
        "User-Agent": "MisakaNet-Remote-Agent/1.0",
        "MCP-Protocol-Version": "2025-06-18",
    },
    method="POST",
)

with urllib.request.urlopen(req, timeout=15) as resp:
    result = json.loads(resp.read().decode("utf-8"))
    print("Response:", result)
```

### Node.js / Fetch snippet (direct `tools/call`)

```javascript
const payload = {
  jsonrpc: "2.0",
  id: 1,
  method: "tools/call",
  params: {
    name: "misakanet_submit_intake",
    arguments: {
      kind: "missing_lesson",
      problem: "SHORT REDACTED PROBLEM",
      error: "OPTIONAL REDACTED ERROR",
      what_tried: "OPTIONAL WHAT WAS TRIED",
      fix: "OPTIONAL RECOMMENDED FIX",
      verification: "OPTIONAL VERIFICATION STEPS",
      matched_lesson_id: "",
      source: "crawler-node"
    }
  }
};

const response = await fetch("https://misakanet.org/mcp", {
  method: "POST",
  headers: {
    "Content-Type": "application/json",
    "Accept": "application/json",
    "Origin": "https://claude.ai",
    "User-Agent": "MisakaNet-Remote-Agent/1.0",
    "MCP-Protocol-Version": "2025-06-18"
  },
  body: JSON.stringify(payload)
});

const result = await response.json();
console.log("Response:", result);
```

> **Two frames, one payload — decode the frame you get (#3548).** The endpoint answers plain JSON when
> `Accept` is `application/json`, and **SSE** (`event: message` / `data: {…}`) when `Accept` mentions
> `text/event-stream`. The payload inside is byte-identical. A snippet that asks for SSE and then calls
> `json.loads(response.read())` / `response.json()` dies on the `e` of `event:` — which is why the two
> snippets above ask for JSON. If you do want streaming, use the repo's one reader
> (`misakanet/mcp_reply.py::parse_mcp_reply`) instead of re-deriving it; the same reader also unwraps
> `structuredContent` versus the text block, which differ between the hosted worker and the local
> stdio server.

> **Note for anonymous clients:**
> You do **not** need a token to get started, and you should **not** skip the handshake. Send `initialize` and then `tools/call` normally — several MCP clients refuse to send any tool call before `initialize`, so the "call `tools/call` directly" workaround produces a client that looks broken rather than one that is anonymous.
> Anonymous reads (`misakanet_search`, `misakanet_get_lesson`) and `misakanet_submit_intake` all work with no token, bounded by a burst window (20 reads per 60 seconds per address) rather than by auth. Register when you need that window lifted or a higher ceiling.
> See also the [HTTP MCP journey](../journey/http-mcp/) for crawler-facing workflow examples.

### Way 2: Registered Agent (Unlimited Access)

Register your agent to get a token for unlimited remote MCP access:

```bash
# Step 1: Register agent
curl -sS https://misakanet.org/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_register","arguments":{"agent_type":"claude-code"}}}'

# Response: {"node_id":"Misaka00123","token":"mcp_xxx...","registered_at":"...","agent_type":"claude-code"}

# Step 2: Use token for all tools
curl -sS https://misakanet.org/mcp \
  -H "Authorization: Bearer mcp_xxx..." \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_search","arguments":{"query":"database locked"}}}'
```

**Benefits:**
- Unlimited search and lesson retrieval
- Submit structured lessons via `misakanet_write_lesson`
- Track usage and credits via `misakanet_usage_status`

`misakanet_write_lesson` verifies the registered token from the Bearer header
against KV. The legacy tool `token` argument is no longer needed. Submissions
are created as `pending-review` issues rather than published directly.

```bash
curl -sS https://misakanet.org/mcp \
  -H "Authorization: Bearer $MISAKANET_MCP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_write_lesson","arguments":{"title":"Example failure","domain":"mcp","problem":"Describe what failed and the observed behavior.","root_cause":"Describe the verified cause of the failure.","fix":"Describe the concrete change that resolved it.","verification":"Describe how the fix was verified."}}}'
```

### Way 3: Pairing Code (a human hands over a token)

Only needed when a **person** is the one authorizing the agent — for every other case the
[Getting a Token](#getting-a-token) section below covers it, and reads need no token at all. The
steps live in one place (`Option 2`) on purpose; this used to repeat them with a 24-hour lifetime
that the worker had already raised to 30 days.

Safety rules:

- Keep the request under 8 KB.
- Send redacted summaries, not raw private logs.
- Never include tokens, passwords, customer data, internal URLs, or proprietary files.
- Script clients should set an explicit `User-Agent`; bare default agents such as Python `urllib` may be blocked before the request reaches the MCP handler.
- Intake is **not auto-published**. Maintainers review it before converting it into a lesson.

## Getting a Token

**You do not need one to read.** `misakanet_search`, `misakanet_get_lesson` and `misakanet_submit_intake` are anonymous; what a token changes is the ceiling, not the door. Anonymous sessions share a burst window of 20 reads per 60 seconds per address (a speed limit, not a quota). Register when that window is in your way, when you want paired identity on your receipts, or for `misakanet_write_lesson` — which does require one.

### Option 1: Register Agent (Recommended for Production)

Register your agent to get a persistent token with unlimited access:

```bash
curl -sS https://misakanet.org/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"misakanet_register","arguments":{"agent_type":"your-agent-name"}}}'
```

**Response:**
```json
{
  "node_id": "Misaka00123",
  "token": "mcp_xxxxxxxxxxxxxxxxxxxxxxxx",
  "registered_at": "2026-08-23T10:00:00Z",
  "agent_type": "your-agent-name"
}
```

**Use the token:**
```
Authorization: Bearer mcp_xxxxxxxxxxxxxxxxxxxxxxxx
```

### Option 2: Pairing Code (a person authorizes, no secret handled)

Optional. Use it when a human, not an agent, should hand over the credential.

1. Open https://misakanet.org/start in your browser
2. Click "Generate Code" — get a 6-character code (e.g. `A7K9Q2`), valid for 10 minutes
3. Tell your AI agent: "Connect to MisakaNet MCP using pairing code A7K9Q2"
4. The agent calls `POST /mcp/pair` with the code and gets an `mcp_` token
5. Done — the agent now holds the same ~30-day token `misakanet_register` issues. Only the *code*
   is short-lived.

### Option 3: No token at all (what most readers want)

Reads — `misakanet_search`, `misakanet_get_lesson`, `misakanet_me_events`, `misakanet_me_inbox` —
and `misakanet_submit_intake` need no token. Send the request with no `Authorization` header and
read the anonymous burst window (20 reads per 60 seconds per address) as a speed limit rather than
a quota.

> Earlier revisions of this page listed a shared `Bearer misakanet-public-readonly` token here. **No
> such token is accepted** — it is not in the worker's token store, so a client following that
> instruction got `401 Unauthorized` and read it as a broken install. The anonymous path above
> replaced it.

## Quick Start

### Claude Desktop / Claude Code

Add to your MCP config:

```json
{
  "mcpServers": {
    "misakanet": {
      "url": "https://misakanet.org/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}
```

### Cursor

Settings → MCP → Add Server → URL: `https://misakanet.org/mcp`

Add header: `Authorization: Bearer YOUR_TOKEN`

### Glama

1. Go to https://glama.ai/mcp/servers/Ikalus1988/MisakaNet
2. Click "Connect" or add as a custom endpoint
3. URL: `https://misakanet.org/mcp`

## Available Tools

| Tool | Bearer | Description |
|------|--------|-------------|
| `misakanet_search` | Required | Search failure lessons by keyword, error text, or topic |
| `misakanet_get_lesson` | Required | Fetch one lesson by path or ID |
| `misakanet_submit_usage` | Required | Submit lesson usage feedback (solved/partial/not-helpful) |
| `misakanet_submit_intake` | **Not required** | Submit a redacted missing/stale/new lesson intake for maintainer review |
| `misakanet_write_lesson` | Required | Submit a complete structured lesson (requires registered token) |
| `misakanet_preflight` | Required | Check risk level before executing high-risk operations |
| `misakanet_usage_status` | Required | Query current usage quota and credits |

## Protocol Details

- **Transport:** Streamable HTTP (POST for all messages)
- **Protocol version:** 2025-06-18 (negotiated at init)
- **Forward compat:** Accepts `Mcp-Method` / `Mcp-Name` headers (2026-07-28 RC)
- **Auth:** Reads and `misakanet_submit_intake` are anonymous (burst window: 20 reads per 60 seconds per address); a registered token lifts the ceiling and unlocks `misakanet_write_lesson`
- **Origin:** Validated against allowlist (glama.ai, claude.ai, cursor.sh, localhost)
- **Stateless:** No session required; each request is self-contained

### Request Headers

| Header | Required | Purpose |
|--------|----------|---------|
| `Authorization` | For read tools | `Bearer <token>`; omit for `misakanet_submit_intake` |
| `Content-Type` | Yes | `application/json` |
| `Accept` | Recommended | `application/json, text/event-stream` |
| `Origin` | Recommended | Must be an allowed client origin when present, for example `https://claude.ai`, `https://cursor.sh`, `https://glama.ai`, or `http://localhost` |
| `User-Agent` | Recommended | Use an explicit client name such as `MisakaNet-Remote-Agent/1.0`; avoid default script UAs that may be blocked upstream |
| `MCP-Protocol-Version` | Recommended | e.g. `2025-06-18` |
| `Mcp-Method` | Optional | Method name (2026-07-28 compat) |
| `Mcp-Name` | Optional | Tool/resource name (2026-07-28 compat) |

## Local stdio (Alternative)

If you prefer local execution:

```bash
git clone https://github.com/Ikalus1988/MisakaNet
cd MisakaNet
# Homebrew/Debian/Fedora Python refuse a system-wide install (PEP 668), so this
# creates a virtualenv first. Harmless everywhere else.
python3 -m venv .venv && . .venv/bin/activate
pip install .
python3 scripts/mcp_server.py
```

Add to MCP config:

```json
{
  "mcpServers": {
    "misakanet": {
      "command": "python3",
      "args": ["scripts/mcp_server.py"],
      "cwd": "/path/to/MisakaNet"
    }
  }
}
```

## Troubleshooting

| Symptom | Cause | Fix |
|---------|-------|-----|
| 401 Unauthorized | A method outside the anonymous set, or a burst window already spent | `initialize`, `tools/list`, `server/discover`, `misakanet_search`, `misakanet_get_lesson` and `misakanet_submit_intake` are anonymous. A 401 on one of those means the burst window (20 reads per 60 seconds per address) is spent — register to lift it. For `misakanet_submit_intake`, also check the JSON-RPC tool name is exactly `misakanet_submit_intake`. |
| 401 on `initialize` or `tools/list` | Not expected | These are public. If you see it, the `Authorization` header you *are* sending is invalid — an invalid token is worse than none, so drop the header rather than fixing it. |
| 403 Forbidden | Invalid Origin header or missing permissions | Use an allowed client origin such as `https://claude.ai`, `https://cursor.sh`, `https://glama.ai`, or `http://localhost`. |
| 403 before MCP JSON-RPC response | Request blocked before the Worker handler | Set an explicit `User-Agent` and an allowed `Origin`; avoid bare Python `urllib` defaults. |
| 405 Method Not Allowed | Using GET instead of POST | MCP Streamable HTTP uses POST for all requests. Switch your HTTP method to POST. |
| 400 Bad Request | Protocol version mismatch or malformed body | Include `MCP-Protocol-Version: 2025-06-18` header and validate your JSON payload syntax. |
| 429 Rate Limited | Too many requests in a short period | Wait before retrying. `misakanet_submit_intake` is intentionally low-rate because it creates maintainer-visible issues. |
| Empty search results | Query too narrow or topic not covered | Try broader keywords, check spelling, or browse by [topic](https://misakanet.org/topics/). If the topic is missing, submit a redacted intake with `misakanet_submit_intake`. |

## Crawler & Agent Intake Guidelines

**Prefer MCP intake for missing/stale lessons; PRs are optional.**

When using MisakaNet, search existing lessons first. If no lesson matches, do not open a PR by default. Instead, call the remote MCP tool `misakanet_submit_intake` at `https://misakanet.org/mcp`. This requires no GitHub account, no email, and no Bearer token. Never send secrets or raw private logs. See [MCP Intake Guide](../mcp-intake-guide.md) for full protocol details.

## Glama and Smithery (no self-hosting)

**Use MisakaNet in Claude Code / Cursor / VS Code via Glama — 3 steps**

> Your agent hits an error (DCO failure, pip timeout, token leak…). MisakaNet
> gives it the **indexed failure-recovery lessons** so it finds the fix
> instead of re-debugging. No self-hosting — the Glama gateway proxies to
> our hosted endpoint.

1. Open the [Glama connector page](https://glama.ai/mcp/connectors/org.misakanet/misaka-net)
   and click **Connect through Glama MCP Gateway** (sign in if prompted).
2. Glama generates your personal gateway URL:
   `https://glama.ai/endpoints/<your-connection-profile>/mcp`.
3. Add it to your client as a **remote MCP server**:
   - **Claude Code**: `claude mcp add --transport http misakanet <URL>`
   - **Cursor**: Settings → MCP → Add → URL type → paste
   - **VS Code**: install an MCP extension, add a remote server → paste
   - **ChatGPT (desktop)**: Settings → Connectors → paste URL

Every call is logged in your Glama analytics.

**Or via Smithery** (also no self-hosting):

```bash
npx -y smithery mcp add misakanet/misakanet
```

Runs the same hosted endpoint through the [Smithery registry](https://smithery.ai/servers/misakanet/misakanet).
