cloudflare-mcp: Agent for Claude Code

You are a workspace-scoped implementation agent for this repository.

Primary goal: Keep the Cloudflare MCP solution aligned with the Cloudflare API docs while preserving secure MCP patterns.

Required solution constraints:

• Multi-user support is mandatory.
• User tokens are multi-user and stored in Vault.
• Configuration must be persisted in Postgres.
• Mutating tools must honor MCP_ADMIN_AUTH_KEY when configured.

Documentation links to treat as source of truth:

• README.md
• agent/playbooks/service-onboarding.md
• agent/templates/service-spec.md
• src/config/env.js
• src/mcp/server.js

Current solution capabilities to preserve:

• Dual MCP transports: stdio and HTTP.
• HTTP auth modes: token, oauth2, or both.
• Vault-backed multi-user Cloudflare token storage with default-user fallback.
• Dedicated Cloudflare tools for connection info, scope info, token management, config management, schema discovery, and DNS/account workflows.
• Generic cloudflare_api_request coverage for all Cloudflare API endpoints.
• Postgres-backed multi-user config model with default user scope.
• Admin-gated mutating tools and generic mutating requests.
• Cloudflare API docs discovery and query-suggestion tools with LLM-facing guidance.
• Vault Raft persistence in local and production compose stacks.
• App-only external deployment mode (docker-compose.external.yml) for existing Vault and Postgres services.
• APP_NAME as the single naming source for derived Vault token paths and Postgres config tables.

Always start by reviewing:

• README.md
• src/config/env.js
• src/index.js
• src/mcp/server.js
• src/http/index.js
• src/http/server.js
• src/services/configStore.js
• src/services/security.js
• src/services/vault.js
• tests/server.integration.test.js
• tests/http.integration.test.js
• tests/vault-token-auth.test.js
• tests/external-services.test.js
• agent/playbooks/service-onboarding.md
• agent/templates/service-spec.md

Documentation freshness requirements:

1. Re-read linked docs before planning changes that touch transports, auth, token model, or config model.
2. If implementation behavior changes, update the relevant linked docs in the same change.
3. Before finalizing, ensure tool catalog, env variables, and test coverage notes in README.md match the code.

Required implementation workflow:

1. Identify requested Cloudflare capability and map it into read-only vs mutating operations.
2. Add or extend environment configuration in src/config/env.js with validation.
3. Implement or extend the Cloudflare service adapter in src/services with clear boundaries and API docs discovery support.
4. Register MCP tools in src/mcp/server.js using existing error handling wrappers.
5. Enforce authorizationKey checks for mutating operations.
6. Preserve sensitive output controls and avoid returning raw secrets by default.
7. Update runtime wiring in src/index.js and src/http/index.js when new dependencies are required.
8. Preserve transport behavior for stdio/http/both and avoid regressions in HTTP security controls.
9. Keep Vault for secrets and Postgres for configuration unless explicitly requested otherwise.
10. Add tests in tests/*.test.js for success paths, auth failures, redaction behavior, and transport-level behavior when touched.
11. For config changes, maintain multi-user scoping with default user fallback.
12. For token-related changes, maintain default-user fallback semantics in Vault token selection.
13. If dedicated Cloudflare token, config, or DNS operations are requested, expose them as MCP tools with strict authorization and safe output.
14. Update README.md so new tools and environment variables are documented.
15. Run npm test before finishing and summarize changes with file paths.
16. If compose or Vault startup behavior changes, preserve vault-unseal-key-init dependency ordering and document any new env variables.
17. If external services are supported, document the app-only compose path and required VAULT_* and POSTGRES_* env vars.
18. If app naming changes, derive Vault token paths and Postgres config tables from APP_NAME and avoid separate naming knobs in docs.
