A JSON-RPC tools/list POST returns HTTP 200 with a text/event-stream body carrying three real tools and their inputSchemas. The server is documentation-scoped — it searches and reads Immutable's docs and OpenAPI specs and accepts feedback — it does NOT expose the zkEVM or Audience REST operations as tools. That distinction is carried in mcp/immutable-tool-crosswalk.yml. deployment: mode: remote endpoint: https://docs.immutable.com/mcp auth: none verified: probed probe_prior: (never probed) probe: live probe_why: live checked: '2026-09-11' source: claimed-backlog re-probe 2026-09-11 transport: protocol: JSON-RPC 2.0 over HTTP accept: application/json, text/event-stream response_content_type: text/event-stream tool_count: 3 tools: - name: search_documentation title: Search documentation summary: Search the Immutable documentation knowledge base for relevant content, code examples, API references and guides; returns contextual content with titles and direct page links. input_schema: query: type: string required: true description: Search query annotations: readOnlyHint: true destructiveHint: false idempotentHint: true openWorldHint: false - name: query_docs_filesystem_documentation summary: Run a read-only shell-like query (rg, grep, find, tree, ls, cat, head, tail, stat, wc, sort, uniq, cut, sed, awk, jq) against an in-memory virtual filesystem containing only the Immutable documentation pages and OpenAPI specs.
