Kosa Developer Documentation

Kosa exposes a venture firm's authenticated records to agents and command-line workflows through one tool layer. Access requires an early-access Kosa account. API keys are issued to early-access firms.

Start here

• Kosa MCP Server: Connect an MCP client, authenticate, and browse the live tool catalogue.
• Kosa API: Call the tools catalogue, execution, and stored-output routes over HTTP.
• OpenAPI 3.1 specification: Read the machine-readable contract for the tools API and MCP endpoint.
• Kosa CLI: Authenticate and use Kosa tools from a terminal.
• OAuth protected resource metadata: Discover the protected MCP resource and its authorization server.
• OAuth authorization server metadata: Discover authorization, token, registration, scopes, and PKCE support.
• llms.txt: Read the machine-oriented site overview and guidance for agents.

Access

Kosa supports OAuth bearer tokens and Kosa API keys on its tools surface. OAuth clients discover the authorization flow from the metadata URLs above. Early-access firms can use an issued API key as a bearer token.
