finos-mcp-fdc3

A read-only MCP server for FDC3: the standard intents, context-type schemas, context validation, and intent suggestion for a given context.

Not affiliated with or endorsed by FINOS. This is an independent, community package. On PyPI the finos- prefix is also used by official FINOS packages such as finos-cdm; this is not one of them.

Run it

Requires Python 3.12+.

uvx --python 3.12 finos-mcp-fdc3                                   # stdio

Tools

• list_intents, get_intent, search_intents, find_intents_by_context.
• list_context_types, get_context_schema, validate_context: issues carry a JSON path and a kind.
• suggest_intent: from a context object or type, optionally re-ranked by a goal.
• server_info.

Safety

Read-only by construction: every tool is registered with readOnlyHint: true and the server refuses to serve tools otherwise. Content is vendored into the package with recorded upstream commit hashes, so the server makes no network calls at runtime. Every call is rate-limited, input-capped, audited as one JSON line, and fails with a structured error the agent can act on. Details: finos-mcp-core.
