StackFast FractWin Expert Brain is a remote MCP server that gives an AI agent 74 tools, among them ai_receptionist_callback_packet, ai_receptionist_review_queue, ai_receptionist_status. It answers at https://stackfast.ai/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Expert knowledge base for sales, negotiation, strategy, operations, and risk.

The zero-cost Gemini reconciliation stage requires exact dispatch, task, job, source, and Chief Editor receipt binding and cannot mint verification. Cost-bearing canary/full-chunk stages require exact pr Inputs: package_id, stage, dispatch_id, verification_task_id, verifier_job_id, segment_id |
cogentcast_production_status | Read tenant-scoped Work Sample, narration-review, or audiobook-production state; exact hashes; current-vs-historical derivative projection; and Chief Editor/Gemini/ear/paid/publication gates. Private source bodies and blob locations are not Inputs: package_id |
credentials_inventory | Discover wallet-resolved credential service names and accepted aliases without exposing secret values. Use this when an agent is unsure whether a key exists, sees a key-not-found error, or needs the canonical getAgentKey(service) name. Retu Inputs: query |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://stackfast.ai/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
