How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to Weavatrix/weavatrix). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 44 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability51
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 13420 tokens (~200/item across 67 items; 67 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage82
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 45% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 67 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 68 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the Weavatrix MCP server?
Weavatrix runs locally as an npm package, launched with npx -y weavatrix. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
npm · weavatrix
claude mcp add weavatrix-weavatrix -- npx -y weavatrix
What is the Weavatrix MCP server?
Weavatrix is an MCP server listed in the public MCP registry as io.github.Weavatrix/weavatrix. Native Weavatrix MCP: 67 read-only tools for code, local CI, n8n, Dify, agents, Mermaid, Web3. This page covers its npm package (weavatrix).
Is the Weavatrix MCP server safe to use?
Weavatrix scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Weavatrix MCP server expose?
Weavatrix exposes 67 tools: graph_stats, get_node, get_neighbors, query_graph, god_nodes, and 62 more. Their descriptions and schemas cost roughly 13,404 tokens of context every time the server is loaded.
Is the Weavatrix MCP server still maintained?
Weavatrix is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the Weavatrix MCP server under?
Weavatrix declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
