Pica
One API connecting AI agents to 100+ third-party services
About
Pica is a unified API platform that connects AI agents to third-party services such as CRMs, email, calendars, and databases. You connect accounts once in the Pica dashboard, and the agent accesses them through tool calling; the vendor claims more than 200 supported platforms. It exposes its capabilities through an MCP server distributed as @picahq/mcp, plus SDKs and a CLI for managing connections.
Vendor-published integration guides cover the OpenAI Agents SDK, Vercel AI SDK, Mastra, and CrewAI. Authentication runs through a PICA_SECRET key, and the company positions Pica as the managed auth and action layer so agent builders do not hand-roll per-service OAuth.
What it can do
- Unified API across 200+ third-party platforms (vendor-claimed)
- MCP server for agent tool calling
- Managed OAuth and credential storage
- Prebuilt skills for OpenAI Agents SDK, Vercel AI SDK, Mastra, CrewAI
- CLI for account connections
- Per-connection scoping
Setup
- Sign up at picaos.com and get a secret key from the dashboard
- Connect your accounts (Gmail, CRM, etc.) under Connections
- Add the MCP server to your agent config: npx @picahq/mcp with PICA_SECRET set
- Let the agent discover and call the connected tools
Prerequisites
A Pica account with API key, and an agent framework with MCP client support.
