mcp-server: Instructions file for Claude Code

CLAUDE.md

mcp-server CLAUDE.md is an instructions file for Claude Code from Repliers-io/mcp-server. It costs 3,097 tokens per session, scanned A, original, MIT.

A set of Claude Code instructions for an MCP server that exposes a real-estate listing API to AI agents. An API is a structured way for software to request data and actions from another service.

In plain words
What is it for?
Use it when developing or maintaining the server, running it over standard input or HTTP, testing it, listing available tools, or regenerating tools from the API specification.
Why use it?
It gives agents the project's architecture, commands, testing guidance, and rules for changing generated API tools safely.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths.

This is Repliers-io/mcp-server's own configuration. It tells Claude Code how to work on mcp-server itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-server configures →

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 CLAUDE.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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repliers MCP Server — Agent Instructions

MCP server exposing the Repliers MLS API to AI agents (claude.ai connectors, IDE agents, custom clients). ESM, @modelcontextprotocol/sdk. One entry point, two transports: stdio (default) and Streamable HTTP (node mcpServer.js --http, served at both /mcp and / on PORT, default 3001). Node version is pinned in .nvmrc and package.json#engines; .npmrc sets engine-strict, ignore-scripts, save-exact and min-release-age=7, so lifecycle scripts never run on install and new dependencies get exact versions.

Scripts are in package.json. npm test is fully offline — fetch is mocked and test/helpers/ runs a fake authorization server in-process and spawns a real --http server against it — so a red suite is never "the API is down".

Where work is tracked

Each feature has ../mcp-server-docs/content/<feature>/{design,plan,status}.md (the docs site, a sibling directory; docs/ in this repo is gitignored, so anything written there is lost). status.md is the resume point — read the newest one before starting anything. Currently: mcp-server-docs/content/feedback-v2/status.md (server-side capture, actionable errors, neutral tool text; implemented and reviewed on develop (0664704); eval re-run and manual ChatGPT check pending), mcp-server-docs/content/oauth21/status.md (OAuth 2.1 resource server; blocked on the PropelAuth dashboard) and mcp-server-docs/content/agent-feedback/status.md (shipped; open items listed there). Upstream API defects found by the eval battery: mcp-server-docs/content/repliers-defects-2026-08-29.md.

Known gap in this server: Search_Listings sets no resultsPerPage/fields on the /nlp call and returns the payload verbatim; responses of several MB have exceeded MCP clients' tool-result limits. The 1 MB check in lib/feedbackHints.js only appends a nudge, it does not truncate.

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.
