The endpoint is live and speaks JSON-RPC 2.0, but its tool list could NOT be introspected: without an MCP-Protocol-Version header it answers HTTP 400 {"error":"A10A10_MCP_PROTOCOL_VERSION_REQUIRED", "required":"2026-07-28"}; with that header, initialize and tools/list in every standard shape (bare, params {}, params._meta.protocolVersion, top-level _meta) return -32600 "Invalid MCP request" or "MCP _meta protocolVersion required". The server's own CORS allow-list names non-standard request headers (mcp-protocol-version, mcp-method, mcp-name), which suggests a bespoke envelope a stock MCP client does not send. The tool names, count and inputSchemas are therefore unknown; nothing below is derived from the OpenAPI to stand in for them. deployment: mode: remote endpoint: https://api.berrergate.com/mcp auth: none verified: probed note: >- A hosted HTTPS endpoint an MCP client POSTs to; BerrerGate ships no stdio package and documents no npx/uvx install (no npm, PyPI, crates, RubyGems or Packagist package exists — see packages/). auth is "none" in the connection sense: no credential is asked for and no OAuth metadata is served on this host (/.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource both 404). Paid actions are settled out-of-band over HTTP x402 (USDC on Base, eip155:8453) — the manifest's own _meta says the MCP surface hands out purchase instructions rather than collecting payment. servers: - id: berrergate name: BerrerGate Tool & Provider Intelligence endpoint: https://api.berrergate.com/mcp transport: streamable-http http_methods: [POST] auth: none payment: none on the MCP surface; purchases happen over HTTP x402 at /v1/agent/beta/query and /v1/research status: live-but-not-introspectable manifest: file: mcp/berrergate-com-mcp-server.json url: https://api.berrergate.com/.well-known/mcp/server.json schema: https://static.modelcontextprotocol.io/schemas/2025-12-11/server.schema.json name: com.berrergate/capability-wisdom version: 1.0.0 declared_protocol_version: '2026-07-28' probe: fetched: '2026-09-19' get_request: {http_status: 404, body: '{"ok":false,"error":"NOT_FOUND",...}'} tools_list_without_version_header: http_status: 400 body: '{"ok":false,"error":"A10A10_MCP_PROTOCOL_VERSION_REQUIRED","required":"2026-07-28",...}' tools_list_with_version_header: request_headers: ['MCP-Protocol-Version: 2026-07-28', 'Accept: application/json, text/event-stream'] http_status: 200 body: '{"jsonrpc":"2.0","id":1,"error":{"code":-32600,"message":"Invalid MCP request","data":{"required_protocol_version":"2026-07-28"}}}' tools_list_with_mcp_method_header: request_headers: ['MCP-Protocol-Version: 2026-07-28', 'MCP-Method: tools/list'] http_status: 200 body: '{"jsonrpc":"2.0","id":1,"error":{"code":-32600,"message":"MCP _meta protocolVersion required","data":{"required":"2026-07-28"}}}' note: >- Also tried with params._meta.protocolVersion, a top-level _meta.protocolVersion, and both at once — same -32600 each time. initialize behaves identically. Seven request shapes in total; none returned a tool list. tool_count: null tools_file: null authorship: provider tools: [] tools_note: >- Unknown — the live tools/list is unreachable with a standard client and the provider publishes no tool reference. The AI Registry catalog entry names three capability labels (ToolDiscovery, CapabilityCheck, PurchaseInstructions) and the A2A card's twelve skills describe the same product surface; see mcp/berrergate-com-tool-crosswalk.yml for the semantic mapping of those to the REST contract, with confidence set accordingly.
