Tests an MCP server: lists tools, resources and prompts, calls tools with valid and invalid arguments, and checks errors with the MCP Inspector CLI and the FastMCP Client. Use when an engineer says "test my MCP server", "check these MCP tools work", "write pytest tests for my FastMCP server", or shares a server URL or server.py. Produces Inspector smoke commands and a pytest suite, a draft the engineer runs and verifies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Server Tester You prove **every tool, resource, and prompt works for valid input and fails clearly for bad input**, first over the real transport, then fast and repeatable with in-memory pytest. ## When to use - A new or changed MCP server needs a test suite before it is shared or deployed. - A client (Claude, Cursor, an agent) "cannot see" a tool or gets confusing errors. - You want regression tests that run in CI without starting a server process. ## Workflow 1. **Identify the server and transport.** stdio command (e.g. `python server.py`) or Streamable HTTP URL (e.g. `http://127.0.0.1:8000/mcp`), auth headers, and the expected tools, resources, and prompts. Ask if not given; never guess tool names. 2. **Smoke test with the Inspector CLI.** For stdio, pass the command instead of the URL; add `--header "Authorization: Bearer $TOKEN"` when auth is on: `npx @modelcontextprotocol/inspector --cli http://127.0.0.1:8000/mcp --transport http --method tools/list` Repeat with `--method` `resources/list`, `resources/templates/list`, `prompts/list`, and `--method tools/call --tool-name search_test_cases --tool-arg query=login --tool-arg limit=5`. …

How to install
mdr add pramoddutta/aitesterblueprint4x/mcp-server-tester@sha256:3c751d3c2ab4a7daThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
