Open-source MCP gateway. One bearer token gives any AI coding agent unified, encrypted access to Vercel, GitHub, Cloudflare, Supabase, GCP, Stripe, Resend, OpenAI, and Anthropic.
Daemoon exposes 22 tools across 9 cloud providers with consistent naming (verb_noun pattern) and structured schemas. Most tools have descriptions and input schemas present. However, many parameter descriptions are minimal or missing, output schemas are undocumented, and error handling lacks recovery guidance. Tool descriptions average ~60 chars (below the 194-char baseline for A+ tools). No tool annotations (readOnlyHint/destructiveHint) despite clear risk stratification. Composition is sound, tools chain well via ID returns, but descriptions don't guide LLM selection between similar tools (e.g., list_projects appears 3 times across providers).
Call the Anthropic Messages API (Claude).
Add a DNS record (A/AAAA/CNAME/TXT etc).
List my zones (domains) registered with Cloudflare.
List my GCP projects.
List enabled GCP APIs/services for a project.
Create a new repo (private by default). description is optional.
Output schemas undocumented. No tool returns a documented schema, LLMs cannot predict response structure for downstream chaining or field extraction.
Missing tool annotations. 8 WRITE tools (create_dns_record, create_repo, send_email, create_payment_link, run_sql, create_project, create_deployment) lack destructiveHint. 14 READ tools lack readOnlyHint. Agents cannot distinguish safe from risky operations.
Minimal parameter descriptions. gcp.list_projects, openai.list_models, resend.list_domains, supabase.list_projects have descriptions under 20 chars. LLMs cannot infer when to call these vs similar tools.

List my GitHub repos (most recently updated first).
List packages published by my npm user (most recently updated first).
View metadata for an npm package (latest version by default). Works for public packages even without auth.
Return the npm username this token belongs to.
Call the OpenAI Chat Completions API.
List model ids available to my OpenAI key.
List my Resend domains.
Send an email. The from-domain must be verified beforehand.
Create a Payment Link for the given price.
List Stripe customers. Filter by email if provided.
List Stripe products.
List my Supabase projects.
Run SQL against a Supabase project. SELECT/DDL/DML all allowed. Useful for creating RPCs.
Trigger a production deployment of a GitHub repo ref (default 'main') to a Vercel project.
Create a new Vercel project. name must be url-safe lowercase.
List my Vercel projects (up to 100). Pass teamId to list a team's projects.
No error recovery guidance. Error responses return raw messages ('Error: <msg>') without actionable next steps. LLMs cannot self-correct or retry intelligently.
Ambiguous list_* tool naming across providers. Three separate list_projects tools (gcp, supabase, vercel) with identical names. LLM must reason about provider context to select correctly, increases hallucination risk.
