Your AI council,
in every tool you use.
One MCP connection gives claude.ai, Claude Code, Cursor, and Windsurf a council of four AI models, reconciled by your agent or synthesized on request. Sign in once. No API keys to paste.
Add a custom connector
Open Settings, then Connectors, then Add custom connector. Name it Synero and paste the server URL.
https://synero.ai/api/mcp
Connect and sign in
Click Connect. Your browser opens a Synero sign-in; approve the connection once.
Ask the council
Try: "Ask the Synero council whether this plan holds up." Four models answer, one synthesis comes back.
What your agent gets
A whole council behind one tool call
One tool, four minds
query_council sends your agent's question to GPT, Claude, Gemini, and Grok at once and returns all four perspectives for your agent to reconcile, or a server-synthesized answer on request. Cross-model consensus as a confidence signal, in a single tool call.
Sized to the question
Auto mode routes each question: trivial lookups get an instant single-model answer in about 2 seconds, hard decisions get a full council. Capped at medium tier with a server-side deadline, so tool calls stay inside your client's timeout.
Sees images
Attach up to 3 screenshots, charts, or photos as base64 data URLs and every advisor analyzes them alongside the prompt.
14+ specialist councils
Pass a template slug and the advisors become domain specialists: code-review, due-diligence, deep-research, devils-advocate, and more.
Your account, your rules
Queries bill exactly like the app: your credits or your own provider keys. Every connection is a named key you can revoke in one click.
Prefer plain HTTP?
The MCP server is a thin wrapper over the REST API. Anything MCP can do, a POST can do too, including streaming, images, and auto tier.

Building an agent?
Synero publishes machine-readable discovery documents so agents connect without a human in the loop.
Framework guides for LangChain, CrewAI, and n8n live on the agent hub.
