mcp-server AGENTS.md

Project instructions for pingrep’s MCP server, a TypeScript service that exposes tools through MCP and connects to the pingrep API.

In plain words
What is it for?
Use them when editing tools, domain types, API clients, use cases, routing, authentication, or when building, linting, and testing the server.
Why use it?
They keep the server’s architecture, authentication, error handling, privacy behavior, and development commands consistent as it changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mcp-server AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

MCP Server Guidance

Applies to mcp-server/ and its subtree.

Stack

  • TypeScript package @pingrep/mcp-server.
  • Clean Architecture layout:
    • src/domain/: tool definitions and domain types.
    • src/application/: use cases.
    • src/infrastructure/: API client, auth, and error mapping.
    • src/presentation/: MCP server setup and tool routing.
    • src/cli.ts: package entry point.
  • Public API defaults to https://api.pingrep.com; PINGREP_BASE_URL can override it.

Commands

  • Install deps: npm install
  • Build: npm run build
  • Typecheck/lint: npm run lint
  • Tests: npm test
  • Watch build: npm run dev
  • Run compiled CLI: npm start

Run these from mcp-server/.

Rules

  • Keep tool schemas and domain types close to src/domain/tools/.
  • Keep HTTP details in the API client and adapter. Use cases should not know transport details beyond interfaces.
  • Preserve public unauthenticated behavior for safe read tools. save_contact and other write/private actions must require auth where the existing contract requires it.
  • Map API errors through the existing error mapper rather than throwing raw HTTP errors.
  • Maintain the privacy rule from the README: MCP tools only expose profiles that are public and MCP-discoverable.

Verification

  • For tool changes, run npm run lint and npm test.
  • For CLI or packaging changes, also run npm run build and a minimal initialize request against node dist/cli.js if practical.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
