MCP SERVERTurn an HTTP API that has no MCP server into one at runtime: register it from a configuration, read back the schema you registered, and call any endpoint through a single generic tool.
No longer maintained. The GitHub repository for this server is archived — no fixes or security updates are expected.
LABSCO SUMMARY
Registration is the whole product: hand it a configuration and the endpoints described in it become callable, either as generated tools or through call_api with an endpoint name. That puts the burden of describing the API on you, and it is worth being clear about what get_api_schema returns — the configuration you registered, not the API's own contract, so a wrong parameter shows up at call time. test_api_connection exists for exactly that gap.
A server that builds MCP tools from API configurations registered while it runs, with a generic call path and a schema lookup beside them.
An HTTP API you can describe in a configuration, and whatever credentials that API itself requires. MIT.
One command — uvx apiweaver run
USE CASES
Describe the endpoints once, check the connection resolves, and start calling. What you registered becomes tools without anyone writing or deploying a server for it.
Check what is registered, read the endpoint's parameters, then make the ad-hoc call through the generic tool rather than committing to a dedicated one.
See what is currently exposed and unregister the one that should not be — its tools go with it, which matters when a configuration held a credential or pointed at production.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
call_apiCall any registered API endpoint with dynamic parameters.
This is a generic tool that allows calling any registered API endpoint without having to use the specific endpoint tools. Useful for ad-hoc API calls or when you want more flexibility.
get_api_schemaGet the schema/documentation for an API or specific endpoint.
This tool helps understand what parameters are available for API calls and their requirements before making actual calls.
list_apisList all registered APIs and their endpoints.
Returns: Dictionary of registered APIs with their configurations
register_apiRegister a new API configuration and create MCP tools for its endpoints.
test_api_connectionTest connection to a registered API.
unregister_apiUnregister an API and remove its tools.
