List

Standalone MCP directory — 61862 servers across 36145 domains, each exposing a remote (streamable-http) endpoint and health-probed via a JSON-RPC initialize handshake.

Add your server

Aggregated from the official MCP Registry, Smithery and other public registries, plus our own crawling and operator submissions. Every server is de-duplicated by endpoint, health-probed via a live JSON-RPC initialize handshake, and statically scanned for malware & prompt-injection patterns in its advertised tools before listing — yielding 61862 indexed servers, of which 53021 answered within the last 6 h.

    Managed knowledge for AI agents: hybrid search, auto-embeddings and live schema introspection over your own collections, behind one endpoint. Agents usually fail at the knowledge layer, not the model. The usual setup is a vector database, an embedding pipeline, a sync job and a hand-written MCP server that drifts out of step with all three. FoxNose replaces that with one managed service that speaks REST and MCP over the same data and the same schema. ## Tools | Tool | What it does | | --- | --- | | `discover_resources` | Lists the collections the key can reach, with their schemas | | `describe_resource` | Returns the live JSON Schema for one collection | | `search_records` | Hybrid search: vector similarity, full text and structured filters in one query | | `query_records` | Filtered, sorted, paginated listing | | `get_record` | Fetches a single record | | `create_record` | Creates a record (requires a key with create grants) | | `update_record` | Updates a record (requires a key with update grants) | Because the agent reads the schema at runtime, you do not describe your data shape in the prompt, and a schema change does not silently break the agent. ## Connecting Create a Flux API key in the dashboard, issue a bearer token bound to it, and paste the token when you add this server. Scopes follow the key: a collection the key cannot read over REST is not reachable over MCP either, so a read-only key is a read-only agent. If the key can read more than one Flux API, set the optional API prefix field. With a single API the prefix is selected automatically. The write tools appear in `tools/list` only when the presented key grants create and update on the selected API. A read-only key sees five tools instead of seven. ## Links - [Documentation](https://foxnose.net/docs/mcp) - [Connect Claude](https://foxnose.net/docs/guides/connect-claude-mcp) - [Connect ChatGPT](https://foxnose.net/docs/guides/connect-chatgpt-mcp) - [Pricing](https://foxnose.net/pricing) — free tier, no card Run by [FoxNose](https://foxnose.net).
