description: >-
  Preferred Networks ships one real MCP server, and it is not for the PLaMo API. The first-party
  plamo-translate CLI starts an MCP server as part of its `server` command, exposing the local
  plamo-2-translate model to MCP clients such as Claude Desktop. It is a local install that a human
  must run on a machine before any agent can reach it; there is no hosted PLaMo MCP endpoint and the
  PLaMo API documentation never mentions MCP.
deployment:
  mode: local-stdio
  endpoint: null
  install: pip install plamo-translate  # then: plamo-translate server
  package: https://pypi.org/project/plamo-translate/
  auth: none
  verified: searched
  note: >-
    Recorded as local-stdio because it is a locally installed server with no vendor-hosted URL. Its
    transport is technically local streamable HTTP rather than stdio: `plamo-translate server` binds
    http://localhost:8000/mcp (start port configurable via PLAMO_TRANSLATE_CLI_SERVER_START_PORT) and
    `plamo-translate show-claude-config` emits an mcpServers entry that bridges to it with
    `npx -y mcp-remote http://localhost:8000/mcp --allow-http --transport http-only`. localhost is
    not an agent-reachable endpoint, so the endpoint field is deliberately left null.

tools:

  method: none
  note: >-
    tools/list was not called. The server does not exist until a user installs the package and starts
    it locally, so there is no remote endpoint this pipeline can POST an introspection request to, and
    no tool list is published in the repository README. The server's capability is translation between
    the languages listed in cli/preferred-networks-cli.yml. Tool names and inputSchemas require a
    local install to enumerate; none are guessed here.

  note: >-
    No hosted MCP server for the PLaMo API was found in the documentation, on the product site, in
    the pfnet or pfnet-research GitHub organisations, or at any well-known path. No endpoint URL was
    guessed.
crosswalk:
  emitted: false
  reason: >-
    A tool crosswalk requires an OpenAPI to bind tools to operationIds. Preferred Networks publishes
    no OpenAPI (see the contract-discovery probes recorded in conventions/ and conformance/), and the one MCP server it
    ships wraps a local translation model rather than the REST API, so there is nothing to bind.
