What it does

ToolFit + MCPCheck is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

6 tools offered to AI assistants

  • audit_tools · Check the tool definitions an agent loads, before they cost tokens or fail: estimated tokens per tool, schema errors per provider (OpenAI, Anthropic, Gemini, Bedrock, MCP; add openai_strict for strict mode) with JSON paths and fixed definit
  • diff_tools · What changed in a tool list since you approved it? Compares "tools" or "url" now with "pin" (set_id from audit_tools/diff_tools) or "baseline" (earlier definitions). Each change is labeled breaking (removed tool or param, new required param
  • check_mcp_server · Does this remote MCP server work, and is it worth connecting or paying for? Sends initialize and tools/list only (never calls a tool) and reports reachability, protocol version, sign-in method (OAuth protected-resource metadata), x402 payme
  • watch_mcp_server · Hosted watch (paid only; this MCP call validates and returns how to pay): ToolFit re-audits a public remote MCP server every 24 h ($0.25) or 6 h ($0.60) for 30 days and POSTs an HMAC-SHA256 signed JSON webhook to your https endpoint when it
  • watch_status · Free: state (active, expired, cancelled), interval, expiry, next check, last result (pin, grade, score, tool count) and webhook delivery counters for a watch. Needs watch_id and the secret returned when it was created.
  • watch_cancel · Free: cancel a watch (no further checks or webhooks; not refunded). Needs watch_id and the secret returned when it was created.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
