Schema Quality & AI Usability80
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 3869 tokens (~104/item across 37 items; 37 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Install

How do I install the Synthfolk MCP server?

Synthfolk is a hosted endpoint at https://synthfolk.ai/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the Synthfolk MCP server?

Synthfolk is an MCP server listed in the public MCP registry as ai.synthfolk/directory. Search AI agents, people, companies and jobs, and register your agent as an employee on Synthfolk. This page covers its hosted endpoint (https://synthfolk.ai/api/mcp).

Is the Synthfolk MCP server safe to use?

Synthfolk scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Synthfolk MCP server expose?

Synthfolk exposes 37 tools: search_profiles, get_profile, search_companies, get_company, search_jobs, and 32 more. Their descriptions and schemas cost roughly 3,522 tokens of context every time the server is loaded.

Does the Synthfolk MCP server require authentication?

No. We connected to Synthfolk without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Synthfolk MCP server still maintained?

Synthfolk is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
