Canonical MCP server resolver. Returns the right MCP for any agent intent with an invocation-ready snippet and an Ed25519-signed trust passport. Cross-registry coverage. npx -y @unfragile/mcp-server

README

Query the Unfragile match graph from any AI agent. Find AI artifacts, discover MCP servers, assemble stacks, compare alternatives, and fetch trust passports. Every query feeds the graph.

Unfragile is built for the agent era: humans click links, agents call capabilities. This server gives Claude Code, Cursor, Windsurf, Claude Desktop, and custom MCP clients a runtime discovery and trust layer for AI artifacts.

Install

Claude Code

claude mcp add unfragile -- npx -y @unfragile/mcp-server

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "unfragile": {
      "command": "npx",
      "args": ["-y", "@unfragile/mcp-server"]
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "unfragile": {
      "command": "npx",
      "args": ["-y", "@unfragile/mcp-server"]
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "unfragile": {
      "command": "npx",
      "args": ["-y", "@unfragile/mcp-server"]
    }
  }
}

Tools

Tool	Description
`search`	Find AI tools by intent. "best framework for building AI agents"
`find_mcps`	Discover MCP servers by capability. "Postgres + Slack integration"
`get_artifact`	Get full details + capabilities for a specific artifact
`resolve_capability`	Resolve a `capability://...` URI to ranked trusted artifacts
`trust_passport`	Get machine-readable trust evidence: capability URIs, permissions, data access risk, failure modes
`compare`	Compare two artifacts side-by-side
`find_stack`	Assemble a complete harness stack for a use case
`feedback`	Report success/failure to improve future routing
`subscribe`	Watch for new artifacts matching a capability need
`unsubscribe`	Cancel a monitor

Examples

Once installed, ask your agent:

"Find me MCP servers for Postgres and Slack"
"Resolve capability://database.postgres.query.readonly"
"What's the best framework for building AI agents?"
"Compare LangChain vs CrewAI"
"Get the trust passport for Cursor"
"I'm building a customer support agent — what tools do I need?"
"Get details on Cursor's capabilities"

How it works

The MCP server calls the Unfragile API under the hood. Search and stack queries become match records in the graph. Trust passport requests use /api/v1/passport/{slug} to return artifact identity, capability URIs, constraints, permissions, data access risk, observed outcomes, and UnfragileRank evidence.

13,160 active AI artifacts. 106,955 capabilities. 24 populated software categories. The match graph for AI.

Environment Variables
