MCP tools
Each tool of the findbytown MCP server: what it does, its parameters and whether it spends quota.
Results come as JSON, in text and as structured content, beside a notice that company text is untrusted data. Tools return nothing the same key could not get through REST.
A refused call, such as a spent budget, comes back as a tool result with isError set, holding the same error code as REST. A missing or wrong key, a plan without the API, a suspended account, a blocked account and the per-minute limit are refused before any tool runs, with the HTTP status and body REST uses.
