Grok WorldGrok Build CLI field station

Retrospective edition / GROK BUILD

Connect MCP servers with a narrow trust contract

Record server identity, transport, authentication, tool namespace, enabled tools, approvals, and diagnostic behavior.

01 / DECIDE

Architecture decision

Use it to add live external tools or context without hard-coding each integration into the agent.

Record server identity, transport, authentication, tool namespace, enabled tools, approvals, and diagnostic behavior. Map input, output, state, tools, and side effects as one observable path, then name the owner of connect mcp servers with a narrow trust contract.

02 / OPERATE

Three-step field procedure

  1. 01

    Lock the contract

    Write down the caller, data classification, success condition, timeout, cancellation, and ownership. Use it to add live external tools or context without hard-coding each integration into the agent.

  2. 02

    Run one bounded path

    Build one end-to-end path with correlation, typed state, and reversible failure handling. Record server identity, transport, authentication, tool namespace, enabled tools, approvals, and diagnostic behavior.

  3. 03

    Verify the signal

    Turn acceptance into a repeatable fixture, contract test, or browser test. Doctor and negative tests verify identity, expired auth, schema drift, unreachable transport, and injected content.

03 / BOUND

Operational boundary

Connect only trusted servers, keep credentials outside committed config, and minimize the exposed tool set.

04 / PROVE

Acceptance evidence

Doctor and negative tests verify identity, expired auth, schema drift, unreachable transport, and injected content.
