Consensus, or the raw answers
What your agent gets
A whole council behind one tool call
One tool, four models
query_council sends your agent's question to GPT, Claude, Gemini, and Grok at once and returns one consensus answer plus exactly where the models agree and split. Pass synthesis: false for each model's raw answer for your agent to reconcile. Cross-model agreement as a confidence signal, in a single tool call.
Sized to the question
The balanced four-model council by default. Pass preset auto and Synero sizes each question, from one model for a quick lookup to a full council for a hard call, or deep for flagship models, slower and costlier. A server-side deadline keeps tool calls 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. Every connection is a named key you can revoke in one click.
What your agent is asking, in the app
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.
