Mcp Eval Runner
Run a standardized test harness against your MCP servers and agent workflows before you ship or publish to a registry.
Overview
MCP Eval Runner is a Ship-phase MCP server that runs a standardized testing harness for MCP servers and agent workflows.
What is this MCP server?
- Standardized testing harness for MCP servers and agent workflows
- Supports pre-ship regression before listing or production use
- npm stdio MCP package mcp-eval-runner
- Aligns with Skillselion-style eval mindset: repeatable runs, comparable results
- YOUR_API_KEY required for eval backend or authenticated runs
- Server version 1.0.0
- stdio npm transport
- Described scope: MCP servers plus agent workflows
What problem does it solve?
Without a shared eval runner, every MCP author manually probes tools in chat and cannot compare regressions across versions.
Who is it for?
Indie MCP authors and agent builders who want repeatable evals before registry publish or customer-facing automation.
Skip if: Pure UI projects with no MCP surface, or teams that only need end-user browser E2E without protocol-level tests.
What do I get? / Deliverables
After install you can execute standardized eval runs against MCP servers and workflows and ship with clearer quality baselines.
- Repeatable eval runs over MCP and agent stacks
- Standardized pass-fail signal pre-launch
- Version-to-version comparison workflow for MCP tools
Recommended MCP Servers
Journey fit
Eval and regression harnesses belong on Ship because they gate quality before launch, alongside other pre-release checks. Testing is the canonical subphase for a standardized runner that scores MCP tool behavior and agent workflow outcomes.
How it compares
Protocol-level eval MCP harness, not a marketing landing skill or generic unit-test framework alone.
Common Questions / FAQ
Who is MCP Eval Runner for?
It is for developers who maintain MCP servers or complex agent graphs and need standardized tests before release.
When should I use MCP Eval Runner?
Use it in ship and testing cycles when you change tools, prompts, or server versions and need comparable eval passes.
How do I add MCP Eval Runner to my agent?
Register mcp-eval-runner as a stdio npm MCP server, set YOUR_API_KEY, and invoke its eval tools from your agent host against target servers.
