Connect a client
Connect an MCP client for setup and a first read-only call. A project-scoped connection uses
/projects/{project_reference}/mcp on the same host.
Find and call a tool
After initialization, use your client’s tool-discovery action to inspect available names and input schemas. A read-only call such asveryfront__list_projects verifies that the client can authenticate and retrieve accessible resources.

Understand availability and results
Discovery describes a tool’s contract; it does not grant permission to call it. A tool can require project access, an external connection, or a particular execution context. Runtime-only tools are documented as agent capabilities and have no direct-call runner. Inspect the JSON-RPC response and the tool result, includingisError when present. Output schemas describe structured results where published. A tool without an output schema is marked explicitly; do not assume its response has a fixed object shape.
The discovery tools expose catalog and error metadata. Tool names and compatibility explains canonical names and existing client behavior.
