Tools
execute_sql— Execute SQL against a configured database source; returns JSON rows. Safety: LIMIT injection on unbounded SELECTs, per-source statement timeout, read-only session enforcement, multi-statement blocking, response byte cap.search_objects— Search for tables by name (Prisma model name or SQL table name). Returns column-level detail: types, nullability, defaults, FK relationships (with join cardinality) and enum values.
About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
