Isometric
by Isometric
Read Isometric's carbon removal protocols, the Isometric Standard, Certify and Registry guides and its OpenAPI specs from your AI agent. 13 tools, OAuth sign-in, a client-side read-only header, and 8 of 13 tools that describe the server rather than return your data.
Verified connector
Listed by Anthropic as a partner connector in its Connectors Directory.
Connection checked by Agentman on .
Anthropic states this reflects the level of review a connector received, not a security audit.

Frequently asked questions
Do I need an Isometric account to use the MCP server?
Yes. Isometric's MCP documentation states you need a user account on the Certify or Registry platform to connect, and our own probe of the endpoint returned a 401 with an OAuth challenge on 2026-08-18. There is no anonymous or public tier. Protocols and the Standard are published openly on Isometric's registry website, but reaching them through this connector still requires a platform login.
Is the Isometric MCP connector read only?
No, but you can make it behave that way. Isometric's documentation says most tools only read data while a few make changes on your behalf, naming commenting on an issue and submitting feedback. Sending the header X-Isometric-Read-Only with the value true makes the server hide every tool that changes data and refuse the call if an assistant asks for one anyway.
What does the X-Isometric-Read-Only header actually do?
It narrows the tool list the server advertises to your client and rejects write calls at the server. Isometric decides which tools remain, so you never maintain a list yourself. Isometric is explicit that this is a convenience for clients that want to limit themselves rather than a permission setting, and it does not restrict what you or your team can do elsewhere on the platform.
What OAuth scopes does the Isometric MCP server request?
None are advertised. Isometric's RFC 9728 descriptor at api.isometric.com names the resource and one authorization server and omits the scopes_supported key entirely, which we confirmed on 2026-08-18. Its authorization server metadata lists grant types, PKCE method S256 and support for Client ID Metadata Documents, but again publishes no scope vocabulary. Consent is therefore all-or-nothing rather than per-resource.
Can the connector see my confidential project data?
It authenticates as you, so it can reach what your Isometric login can reach. Isometric's data visibility guide sets out a staged model: draft Project Design Documents, LCAs, removal areas and measurement samples are visible only to the supplier organisation and Isometric until a verifier is assigned or credits are issued. The connector inherits that model, it does not widen it.
Does the Isometric MCP server work with ChatGPT and other clients?
Yes. Isometric pre-approves Claude, ChatGPT, Google Gemini, VS Code with Copilot, Cursor and Mistral for authentication. Other clients work if they support streamable HTTP, MCP authorization, and either Client ID Metadata Documents or pre-registration, for which Isometric accepts any arbitrary client ID with no secret. Redirect and CIMD domains must be allowlisted, so unusual clients may need support to approve them.
Can I connect the connector to the Isometric sandbox instead of production?
Yes. Isometric runs a second MCP server at api.sandbox.isometric.com/mcp wired to sandbox data. The official Claude connector points at production only, so you add the sandbox as a custom connector in the same Claude settings screen. Isometric's API credentials are environment-scoped too, since a client secret is tied to either sandbox or production and cannot span both.
