Sign in to the hosted MCP server without a key
The hosted MCP endpoint at https://api.onegoodarea.com/mcp now supports OAuth sign-in. In Claude, add it as a custom connector and sign in with your OneGoodArea account; in Claude Code, add it with claude mcp add --transport http and authenticate from /mcp. Approving creates an API key named after the app in your account, metered like any other, and revoking it from your dashboard disconnects the app. Header keys keep working for clients that cannot sign in.
Hosted MCP endpoint
The twelve MCP tools are now served by the API itself at https://api.onegoodarea.com/mcp over Streamable HTTP, so a client reaches them with nothing to install. Every tool call runs through the same API routes as a direct call, under the same key, plan and allowance. The npm package and the MCP Registry listing continue for clients that spawn a local server.
A Claude plugin with four skills
The public oga-mcp repository now carries a Claude plugin: the hosted connector plus four skills that teach Claude how to research an area for a lender, compare sites for retail, read confidence and observation dates, and watch a portfolio for change. Each skill is written from the methodology and the tool definitions. Until the Claude directory lists it, claude --plugin-dir runs it locally.
resolve_place in the MCP server
MCP server 1.0.13 adds resolve_place: a postcode, place name, official code or place id becomes the permanent place it names, with how it resolved and whether a postcode is live or retired. Every tool now carries a title and a read-only hint, and its description names the coverage as England, Wales and Scotland.
The sandbox allows 500 calls and 100 questions a month
The free sandbox moves from 200 to 500 calls a month, with a ceiling of 100 a day, and from 10 to 100 natural-language questions. Sandbox questions now answer on a paid model first, so a first question after a quiet spell no longer waits on a free host.
MCP access on every plan with API access
Every plan with API access now includes the MCP server, from the free sandbox to the platform licences. Nothing extra to buy.
Training capture is off by default
New API keys no longer feed natural-language questions and explained scores into OneGoodArea's training logs unless their owner switches capture on. Existing keys that never changed the old default are switched off too; the Training switch in the console opts a key back in.
