Automate protocol assertion tests, benchmark execution latency, and validate JSON-RPC 2.0 tool schemas for Claude Desktop, Cursor, Zed, and WebMCP servers. 100% client-side memory privacy ensures your test payloads and API keys stay on your device.
Manifest valid for 'Filesystem MCP Server Test Suite' (filesystem)
Validated 3 test request frames
Protocol handshake test case included with capabilities check
Tool discovery schema validation passed
Tool call argument schemas match target constraints
Zero unmasked secrets detected in test suite payload
Execution latency: 28ms | Payload: 2276 bytes
Choose a starter test suite preset (Filesystem, Brave Search, Memory, PostgreSQL, or Custom) or edit the JSON test manifest directly.
Execute 8+ automated assertion checks validating JSON-RPC 2.0 spec compliance, handshake capabilities, tool schemas, and secret redaction.
Export copy-paste integration test suites for TypeScript (`@modelcontextprotocol/sdk` + Vitest) and Python (`pytest-asyncio`) for automated CI pipelines.
Zero backend network calls. All MCP test suites, request frames, mock tool parameters, and API keys are executed strictly in local browser memory.
Runs 8+ automated assertion checks including JSON-RPC 2.0 spec validity, initialize capabilities handshake, tools/list schema compliance, and standard error code handling.
One-click starter mocks for Filesystem MCP, Brave Search MCP, Memory MCP, PostgreSQL MCP, and Custom JSON-RPC Endpoint testing.
Measures response execution time (ms), payload byte size, token density estimates, and throughput metrics across repeated mock runs.
Scans test request payloads and environment configs for unmasked tokens (sk-, ghp_, Bearer) and auto-redacts them before report export.
Export ready-to-run automated test scripts for TypeScript (@modelcontextprotocol/sdk + Vitest/Jest) and Python (pytest-asyncio + mcp).
Our MCP Test Suite is open source under HiMat Technologies. Star the repo or contribute test adapters on GitHub.
HiMat's MCP Server Test Suite operates 100% locally in client browser memory. Neither your tool arguments, database queries, file paths, nor API credentials are ever sent to HiMat or any third-party servers.
It is an automated testing and performance evaluation harness for Model Context Protocol (MCP) servers. It validates JSON-RPC 2.0 protocol compliance, checks initialize handshakes, verifies tool call schemas, measures execution latency, and ensures robust error handling.
No. The HiMat MCP Server Test Suite operates 100% locally in your web browser. Neither your test cases, mock tool arguments, local file paths, nor API credentials ever leave your device.
The test suite validates standard MCP protocol methods including initialize, notifications/initialized, tools/list, tools/call, resources/list, resources/read, prompts/list, and custom notification frames.
Yes! The test suite generates copy-paste test suites for TypeScript (Vitest/Jest with @modelcontextprotocol/sdk) and Python (pytest-asyncio with mcp) to automate regression testing in GitHub Actions.
Yes, 100% free with no account registration required, no daily usage caps, and zero advertisements.
