A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.
Your agent needs creators who actually fit — starting from one profile you already like, or from a brief — and then a way to reach them. **What you can ask for** • "Find creators similar to this profile, in this country." • "Who else makes content like this account, with a comparable audience?" • "Look up the contact email for this creator." • "Build a shortlist for this brief and give me the emails." **How to use it** Point any MCP client at https://mcp.aisa.one/creator-discovery/mcp and sign in with OAuth — there is no key to create or paste. 2 tools: similar-creator lookup from a seed profile or a brief, and an email lookup for a creator. **Why this rather than the source** Similarity from a profile you already trust, rather than a filter over a follower-count database. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Shortlist the creators here, then ask the same agent for their posting history on Instagram or X — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/social/mcp for what those creators actually post; https://mcp.aisa.one/sales/mcp for the rest of the outreach.
