 "title": "Give Codex a guarded, authorized MCP catalog",
 "page_title": "How to give Codex a guarded, authorized MCP catalog with MCP Slim Guard",
 "summary": "Route Codex through Slim Guard in Native mode so it sees authorized tools with full schemas.",
 "who": "A developer using Codex on a project with MCP servers who wants the normal tool catalog but with allow/deny checks and call validation in front of it.",
 "problem": "Connecting Codex straight to upstream MCP servers gives no single place to enforce allow/deny rules or check arguments before the upstream is contacted.",
 "outcome": "Codex lists only authorized original tool names with full schemas, and calls are validated before any upstream server is invoked.",
 "steps": [
  "In the reviewed checkout, run `npm ci`, then `npm run build`, then `npm link`.",
  "Change into your project directory and run `mcp-slim-guard init`, then `mcp-slim-guard validate`.",
  "Edit `mcp-slim-guard.yml` so the `tools` allow and deny patterns match what Codex should reach.",
  "Run `mcp-slim-guard plan --host codex` to review the host plan without changing host files.",
  "Run `mcp-slim-guard verify --host codex`, then `mcp-slim-guard install --host codex --mode native`."
 ],
 "agent_prompt": "Use the lennney/mcp-slim-guard repo to set up Native mode for Codex in the project at <project-path>. Run the plan and verify commands from the README and report the planned host entry. Confirm that `mcp-slim-guard verify --host codex` reports a configured runtime before you apply the install.",

 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The package is an alpha source candidate that is not on npm yet, and the README advises reviewing authorization patterns before using it with privileged tools.",

 "lang": "typescript",
 "requirements": [
  "A reviewed checkout of the lennney/mcp-slim-guard repository (0.1.1-alpha.2 is not yet published to npm)",
  "npm to run ci, build, and link the package",
  "A project directory that already has an MCP configuration",
  "An upstream MCP server definition you are authorized to use"
