    Remote first. The hosted Streamable-HTTP endpoint is the product — an agent reaches it with an
    OAuth token and no local install. The @apolloio/mcp npm package and the apollo-mcp-plugin repo
    are plug-in distributions that point at that same remote URL (their .mcp.json declares
    type "http", url https://mcp.apollo.io/mcp); neither runs a local stdio server.

    tools/list requires an OAuth bearer token, so the live inputSchema set cannot be captured
    anonymously. The tool list below is Apollo's own published "Available actions" table from
    https://docs.apollo.io/docs/apollo-mcp — names and descriptions are verbatim from the provider;
    the machine-readable input schemas need an authenticated introspection pass. The 401 challenge
    itself enumerates the full scope set, which is captured in scopes/apollo-io-scopes.yml.

governance:
  model_training: >-
    Apollo prohibits AI model training with Apollo MCP integrations and asks that model training be
    turned off in the AI client before connecting.
  permissions: >-
    MCP access mirrors the authorizing Apollo user's own permissions, plan and credit balance —
    a tool cannot do anything that user could not do in the app.
  destructive_actions: Bulk delete and other destructive actions are not exposed.
  rate_limits: >-
    Apollo MCP uses rate limits separate from the REST API and does not return the REST
    x-rate-limit-* response headers.
