@pleach/mcp changelog
Release history for @pleach/mcp — site-docs entries that materially touched the @pleach/mcp surface, newest-first. Canonical runtime history lives upstream.
This page collects the site-content changelog entries that
materially touched the @pleach/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 and on
npmjs.org/package/@pleach/mcp.
See the combined site changelog at
/docs/changelog/combined for the
chronological unified view across every SKU.

@pleach/mcpdocs 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 (plusgetSession/listSessions/unregisterSession, last-wins on duplicatesessionId) — theNotImplementedError("D-PA-184")prose and status-table row are gone (server.ts:364).resources/*andprompts/*are dispatched live on theMCPServerwire via both the SDKsetRequestHandlerpath (server.ts:574,595) and the pluggabledispatchPluggableMethod(server.ts:757,767); the two "Not yet exposed; Phase B" table rows moved to Live. The pluggable dispatcher implementsinitialize(case "initialize": handleInitialize,server.ts:740) — the docs no longer claim it returns-32601 Method not found.McpRuntime.registerCapabilitylands resource / prompt kinds in the last-wins ledger without throwing (McpRuntime.ts:207,363) — the "shape stable, body deferred / throws today" section was rewritten. ThecreateSSETransport().start()factory throws a genericError(transport.ts:412); the typedNotImplementedError("D-PA-181")is the options-bagserver.start({ transport: "sse" })path (server.ts:524) — the factory table row and theNotImplementedErrorinstance list were corrected accordingly. -

Both fields now point athttps://github.com/pleachhq/mcp(washttps://github.com/pleachhq, a leftover from when the SKU schemas were drafted against an upstream monorepo).
