Mcp Orchestrator

MCP Orchestrator

MCP (Model Context Protocol) is one of grok-build-0.1's strongest advantages. This skill makes it first-class.

Responsibilities

1. Inventory current state

• Run grok inspect (or equivalent) to see loaded MCPs.
• List project and user-level MCP configuration.

1. Identify the gap

• What real capability is missing for the current task?
• Examples: visual QA, deep git history analysis, session introspection, architecture visualization, external service access.

1. Evaluate and recommend specific MCP servers

• Prefer narrowly-scoped, well-documented servers over kitchen-sink ones.
• Check security model, maintenance, and fit for agent use.
• From this arsenal: recommend agent-session-analyzer, repo-graph, test-intelligence, browser-qa, skill-validator when appropriate.

1. Guide installation and configuration

• Provide exact commands or config snippets.
• Handle trust prompts and .grok/config.toml or project MCP files.
• Create or update skills that know how to drive the new MCP.

1. Integrate into workflow

• After installation, immediately demonstrate value with a small example.
• Update relevant skills or the current plan to use the new capability.
• Document in the project (README, AGENTS.md, or showcase notes).

Safety Rules

• Never install untrusted or overly broad MCP servers without explicit review.
• MCP servers that can execute arbitrary code or access secrets must be treated like hooks — require trust and clear documentation.
• Prefer read-heavy MCPs for investigation phases.

Recommended Arsenal MCPs

• agent-session-analyzer — for meta work on agent behavior
• repo-graph — architecture understanding at scale
• test-intelligence — surgical testing
• browser-qa — when building or changing UIs
• skill-validator — when extending the skill system itself

Success Criteria

• The right MCPs are installed and discoverable via grok inspect.
• There is at least one concrete, working example of the agent using the new MCP in the session.
• Any new skill or documentation needed to make the MCP usable long-term has been created or updated.
