# Truespar

> Truespar builds infrastructure for AI builders - model inference, databases, search, and file tooling that install as a single file on your own hardware, expose APIs compatible with the tools they replace, and ship with published head-to-head benchmarks.

Truespar is a research arm of The Intelligence Company AB (publ), based in Stockholm, Sweden. Each product below is a standalone engine you can run yourself.

## For AI agents
Three free, open endpoints. No account, no API key, no signup - per-IP rate limits only. All are read-only, serve MCP over Streamable HTTP, and are listed together at [MCP & APIs](https://truespar.com/mcp).
- [Truespar Docs MCP](https://mcp.truespar.com/): Search Truespar's docs and site with hybrid keyword + vector search. MCP endpoint `https://mcp.truespar.com/mcp`. One tool, `search_docs(query, product?, limit?)`.
- [Truespar MCP Registry](https://registry.truespar.com/): An index of the public MCP ecosystem, synced daily from the public MCP registries, ranked provenance-first, with every hosted endpoint checked by a real MCP handshake. Answers "is there an MCP for X, and how do I connect to it?". MCP endpoint `https://registry.truespar.com/mcp`, tools `find_mcp_servers(query, category?, tier?, hostable?, limit?)` and `get_mcp_server(key)`. Also REST at `https://registry.truespar.com/v1/servers`, with an OpenAPI 3.1 document at `https://registry.truespar.com/openapi.json`.
- [Truespar LEI API](https://lei.truespar.com/): The GLEIF Legal Entity Identifier golden copy - about 3.4 million registered legal entities worldwide, reloaded daily. Search by name or address, filter by country, jurisdiction, status and legal form, or look up one record by LEI. MCP endpoint `https://lei.truespar.com/mcp`, tools `search_legal_entities(query?, country?, status?, ...)` and `get_legal_entity(lei)`. Also REST at `https://lei.truespar.com/v1/entities`, with an OpenAPI 3.1 document at `https://lei.truespar.com/openapi.json`.
