# @pleach/mcp changelog (/docs/changelog/mcp) This page collects the **site-content changelog entries** that materially touched the [`@pleach/mcp`](/docs/mcp) docs surface or named a `@pleach/mcp` symbol. It is not the runtime changelog — the canonical record of `@pleach/mcp` runtime behavior lives in the upstream package [`CHANGELOG.md`](https://github.com/pleachhq/getpleach) and on [npmjs.org/package/@pleach/mcp](https://www.npmjs.com/package/@pleach/mcp). See the combined site changelog at [`/docs/changelog/combined`](/docs/changelog/combined) for the chronological unified view across every SKU. ## Unreleased [#unreleased] ### Fixed [#fixed] * **[`@pleach/mcp`](/docs/mcp) docs flipped from the pre-Phase-B "throws today" framing to the shipped surface (devharness FINDING 95–99).** `registerSession(sessionId, runtime, { tenantId? })` is a **live** in-memory session registry (plus `getSession` / `listSessions` / `unregisterSession`, last-wins on duplicate `sessionId`) — the `NotImplementedError("D-PA-184")` prose and status-table row are gone (`server.ts:364`). `resources/*` and `prompts/*` are dispatched live on the `MCPServer` wire via both the SDK `setRequestHandler` path (`server.ts:574,595`) and the pluggable `dispatchPluggableMethod` (`server.ts:757,767`); the two "Not yet exposed; Phase B" table rows moved to Live. The pluggable dispatcher implements `initialize` (`case "initialize": handleInitialize`, `server.ts:740`) — the docs no longer claim it returns `-32601 Method not found`. `McpRuntime.registerCapability` lands resource / prompt kinds in the last-wins ledger without throwing (`McpRuntime.ts:207,363`) — the "shape stable, body deferred / throws today" section was rewritten. The `createSSETransport().start()` **factory** throws a generic `Error` (`transport.ts:412`); the typed `NotImplementedError("D-PA-181")` is the *options-bag* `server.start({ transport: "sse" })` path (`server.ts:524`) — the factory table row and the `NotImplementedError` instance list were corrected accordingly. * **Schema `codeRepository` + `sameAs` for [`@pleach/mcp`](/docs/mcp) corrected** in the site's Organization + SoftwareApplication JSON-LD `@graph` (inlined in `` on every page). Both fields now point at `https://github.com/pleachhq/mcp` (was `https://github.com/pleachhq`, a leftover from when the SKU schemas were drafted against an upstream monorepo). Load-bearing because `sameAs` is the field AI search engines use for entity reconciliation across the npm ↔ GitHub ↔ docs boundary. See the [combined view](/docs/changelog/combined) for the full cross-SKU pack. ## 2026-06-08 [#2026-06-08] ### Changed [#changed] * [Packages](/docs/packages) table corrected to real published version — `@pleach/mcp 0.3.0-alpha.0` (was largely stale "Reserved · placeholder" framing).
