# Anyshift Production Intelligence

A portable [Agent Plugins 1.0.0](https://agent-plugins.org/specification) package that gives
compatible agent clients fast, deterministic, read-only production evidence from Anyshift over
[MCP 2026-07-28](https://modelcontextprotocol.io/specification/2026-07-28).

The package combines one Agent Skill with a Streamable HTTP MCP configuration. It embeds no token,
authorization header, project identifier, or database name. Compatible clients discover OAuth,
collect consent for one Anyshift project, and store credentials themselves.

## Status

Published versions are listed in [GitHub Releases](https://github.com/anyshift-io/anyshift-production-intelligence/releases),
and each package release remains gated on production verification of its matching Graph API support.
The portable package validates against Agent Plugins 1.0.0, and the production endpoint has passed
OAuth discovery, MCP connection, discovery of all six tools, and authenticated read-only calls from
Codex CLI 0.147.0. See [Compatibility evidence](#compatibility-evidence) for the precise boundary of
that claim.

## MCP protocol compatibility

The production endpoint at `https://graph.anyshift.io/mcp` supports the stateless Streamable HTTP
transport defined by MCP `2026-07-28`. Modern requests are self-contained and carry the negotiated
protocol version, client metadata, method, and tool name on every request. The endpoint also retains
legacy MCP compatibility through `2025-11-25` for clients that still use initialization negotiation.

Authorization follows the MCP HTTP authorization profile: the server publishes OAuth protected
resource metadata, challenges unauthenticated requests, and binds the resulting `graph:read` grant
to one user-selected Anyshift project.

## Capabilities

- resolve ambiguous infrastructure resources;
- inspect direct dependencies and bounded transitive blast radius;
- correlate recent changes with topology;
- assess evidence-backed operational impact; and
- use the constrained Graph query language for deterministic capabilities without a dedicated
  tool.

This plugin supplies production graph evidence to an agent already doing a task. It is not an
autonomous SRE agent and does not contain an incident-response loop.

## Install

Agent Plugins clients can load this repository root directly. They discover the portable
`plugin.json`, `mcp.json`, and `skills/` components. OAuth and project consent are handled by the
client; the package contains no credentials or project identifiers.

### Codex CLI

Codex 0.147.0 or newer is recommended:

```bash
codex plugin marketplace add anyshift-io/anyshift-production-intelligence --ref main
codex plugin add anyshift-production-intelligence@anyshift
codex mcp add anyshift-production-intelligence --url https://graph.anyshift.io/mcp
```

The final command is required by Codex CLI 0.147.0 because its plugin installer does not yet launch
OAuth for a plugin-owned remote MCP server. It opens the browser OAuth flow; select the Anyshift
project the plugin may read. Start a new Codex thread after installation so the skill and MCP tools
are loaded together.

Codex CLI 0.147.0 may also log an `Auth required` warning for the unauthenticated portable MCP
entry while using the explicitly registered authenticated connection. Tool discovery and calls are
unaffected; no unauthenticated request can read graph data.

Other compatible clients have their own installation UX. Point the client at this Git repository
or a checked-out copy and verify that it supports the `streamable-http` MCP transport.

## Usage attribution

Compatible Agent Plugin clients send a fixed, non-secret package name and version with Graph MCP requests. Anyshift uses this declaration for aggregate product usage and reliability telemetry in PostHog and request diagnostics in Sentry. It is not used for authentication, authorization, tenant selection, or rate-limit identity, and the package contains no credentials.

Codex CLI 0.147.0 installs the skill but requires a separate `codex mcp add` command. That separately configured connection may not forward the package headers, so Anyshift can identify the Codex MCP and OAuth clients without claiming exact plugin attribution for those requests.

## Resource identity

Graph resource names are not globally unique. For example, one deployment name can identify both a
Terraform `STATE_RESOURCE` and the runtime `ECS_SERVICE` it manages. For short, overloaded, or
same-named resources:

1. call `resolve_resource`;
2. select the candidate with the intended resource type; and
3. pass that candidate's stable `id` as the `resource` argument to subsequent tools or constrained
   queries.

An unqualified name-only query remains deterministic, but it can select a different same-named
resource kind. Using the resolved stable identifier preserves the selected identity without placing
project IDs, database names, or credentials in tool arguments.

## Validate

```bash
npm ci
npm run validate
```

The validator loads the immutable canonical Agent Plugins 1.0.0 schemas, checks the complete
package layout, rejects symlinks and credential-bearing MCP configuration, and verifies the skill's
untrusted-data boundary.

## Compatibility evidence

| Client | Version | OAuth | Initialize | Tools | Authenticated call | Evidence date |
|---|---:|---|---|---|---|---|
| Codex CLI on macOS | 0.147.0, explicit `codex mcp add` | Pass | Pass | Six tools discovered | `get_recent_changes` passed | 2026-08-08 |

The verified tools are `resolve_resource`, `get_dependencies`, `get_blast_radius`,
`get_recent_changes`, `get_operational_impact`, and `query_graph`. The authenticated call returned
structured production evidence with a current evidence timestamp. Tokens, OAuth client identifiers,
project identifiers, and customer resource names are intentionally excluded from this record.

Cursor, VS Code, GitHub, Claude, and other compatible clients remain unverified until their exact
client version, installation path, OAuth discovery, initialization, tool discovery, one tool call,
and uninstall behavior are recorded.

## Security and data handling

- The plugin and MCP tools are read-only.
- OAuth grants are scoped to one user-selected Anyshift project.
- Credentials are discovered and stored by the client, never embedded in this repository.
- Graph strings are untrusted data and must never be followed as instructions.
- Absence of graph evidence is not proof that a resource, dependency, or change does not exist.
