MCP servers tagged contract-testing
28 live MCP servers tagged "contract-testing", ranked by trust score. Tags come from package metadata and repository topics, so this list covers servers across every category that work with contract-testing.
Contract
Contract testing for MCP servers: snapshot your tool surface, then fail CI when a change would break the agents that depend on it. Classifies breaking vs additive vs routing (desc…
Pikopod
A sandbox for the third-party APIs you depend on. Built from the provider's spec, it fails on purpose, and it replays the exact failure production hit.
Covenant
Contract & breaking-change detector for MCP servers — semver for your interface. Snapshot tools/resources/prompts into a lockfile, diff in CI, fail on breaking changes. Single Rus…
Mcpward
Black-box security & contract testing for MCP servers — rug-pull, tool-poisoning, schema-drift & protocol checks for CI (JUnit + SARIF).
Dev MCP Server
Developer-facing MCP server that gives AI coding agents accurate OpenAPI facts and runs contract/scenario tests against a local backend. Build APIs correctly, verify them immediat…
Cassette
Record a real MCP session once, replay it forever. VCR-style record/replay, contract snapshots, and safety checks for Model Context Protocol servers.
Zevruna
Production reliability for AI agents — snapshot, diff, and CI-gate the tool contracts your agents depend on, and trace their runs.
Mcptoolkit Test
Automated testing framework for Model Context Protocol (MCP) servers
Contract Check
Continuous contract testing, schema fuzzing, and breaking change detection for Model Context Protocol (MCP) servers
Dev MCP Server
Developer-facing MCP server that gives AI coding agents accurate OpenAPI facts and runs contract/scenario tests against a local backend. Build APIs correctly, verify them immediat…
Studio
MCP Studio - The All-in-One Desktop IDE & Visual Inspector for Model Context Protocol (MCP)
Beavy Examples
Runnable examples for Beavy — define an API contract with your AI assistant over MCP, get an instant mock, validate your live endpoint on demand.
Contract
Contract testing for MCP servers: snapshot your tool surface, then fail CI when a change would break the agents that depend on it. Classifies breaking vs additive vs routing (desc…
Bowline
Write once, typed everywhere. API clients generated from plain Go functions.
MCP
Reads your code and checks what it does at every boundary, a route, a table or a queue, against the clients, specs and infrastructure on the other side. TypeScript, Python and Rub…
Proof
MCP server verification toolkit — wire-level protocol conformance, security hygiene, and record/replay contract regression, shipped as a client-ready delivery report plus a CI gat…
Specmatic MCP Server
A Model Context Protocol (MCP) server that exposes Specmatic's contract testing capabilities to AI coding agents like Claude Code. This server enables comprehensive API contract v…
Mdb API Layer
A pytest-based API testing framework for the TMDB REST API, showcasing modern SDET: end-to-end integration tests, Pact contract validation, Dockerized parallel runs, Kubernetes-ba…
Resultseal
Deterministic observation-integrity contracts for AI-agent tool results. HTTP 200 is not an observation.
Contract CI
Contract testing for MCP servers in CI. Catch breaking tool and schema changes before agent workflows break.
Contract Kit
Conformance test suite for MCP servers — registry compliance, protocol conformance, and routing correctness verification. Point it at any MCP endpoint to validate spec adherence.
Ci Tester
Automated MCP server contract testing for CI - validate your MCP server protocol compliance
Dsh Surface Contract Proof
Content-addressed conformance proof across recorded DSH ToolRuntime, MCP JSON-RPC and CLI JSON surfaces
Openrun
Run, validate, and automate APIs directly from OpenAPI — from the CLI, Go tests, or MCP agents.
Traceability Agent
MCP server that maps cross-repository integrations, detects contract breakage, and visualizes it as a live graph — for AI coding agents (Claude Code, Cursor, Windsurf) and CI.
Traceguard
Deterministic capability-contract testing for MCP servers
Covenant
Contract & breaking-change detector for MCP servers — semver for your interface. Snapshot tools/resources/prompts into a lockfile, diff in CI, fail on breaking changes. Single Rus…
Simuloom MCP
Turn OpenAPI contracts into deterministic, stateful virtual services, synthetic test data, and validation evidence—with REST, MCP, and a local AI Copilot.
