Unfragile MCP server

Read from the package source without running it. The installed server may list more.

• compare

  Compare two AI artifacts side-by-side. Shows capabilities, pricing, rank, and graph signals for each. Uses search-based lookup (best-effort name matching). Use this when deciding between alternatives.

• feedback

  Report whether a recommended tool worked or not. This closes the learning loop — the Unfragile graph uses this feedback to improve future recommendations. Call this after trying a tool from search results.

• find_mcps

  Find MCP servers by capability need. Use this when you need to discover MCP servers for specific integrations (e.g., databases, APIs, cloud services). Returns MCP servers ranked by capability match.

• find_stack

  Assemble a complete AI harness stack for a use case. Given a description of what you're building, returns recommended tools across harness layers: orchestration, tools/MCPs, memory, guardrails, context assembly, and evaluation. This is the key differentiator — Unfragile understands that modern AI systems are composed of 5-15 tools working together.

• get_artifact

  Get full details and capabilities for a specific AI artifact by name or slug. Uses search-based lookup (best-effort name matching — may return a different artifact for ambiguous names like 'express'). Use this to understand what an artifact can do before adding it to your stack.

• resolve_capability

  Resolve a capability:// URI or natural-language capability into ranked AI artifacts. This is Unfragile's capability DNS primitive. Use when an agent knows what capability it needs and must choose the safest current artifact at runtime.

• search

  Search the Unfragile match graph for AI tools, frameworks, APIs, MCP servers, agents, and more. Returns ranked results with capability matches and graph signals. Every query feeds the graph.

• subscribe

  Set up a persistent watch for new AI tools matching a query. Get notified daily when something new appears in the Unfragile graph. Requires at least one notification channel (email or webhook).

• trust_passport

  Get the machine-readable trust passport for an AI artifact. Use this before an agent selects a tool, API, MCP server, model, repo, or framework for a task. Returns capability URIs, permissions, data access risk, known failure modes, observed outcomes, and trust score.

• unsubscribewrite action

  Cancel a persistent watch (monitor). Use the monitor ID returned from subscribe.
