The MCP server index that vets servers, not just lists them. Advisory screen before you install.
Server tool list (6)
Raw names from tools/list. Only developers need these.
| recommend_mcp_for_task | Recommend the best MCP servers for a natural-language task. Returns top 3 ranked picks with reasoning, install commands, and quality scores. Use this when the user asks for the right MCP server for a task they want to do. |
| search_mcp_servers | Keyword + semantic search across every MCP server mcpindex indexes. Use when the user knows what tool category they want but not which server. |
| get_install_command | Get the exact install command for a given MCP server and client. Returns a JSON block ready to paste into the client config. |
| compare_servers | Side-by-side comparison of 2-5 MCP servers - quality scores, install paths, env vars. |
| check_tool_trust | Pre-invocation advisory screen for a specific tool on an MCP server. Returns an advisory verdict object (directive ALLOW | DENY | REVIEW | UNVERIFIED, dimensions, freshness). At v1 the public screen produces REVIEW or UNVERIFIED only - ALLOW/DENY are reserved. Not the in-path gate (mcpindex-gate). Agents SHOULD treat UNVERIFIED as "human review required", never as ALLOW. |
| assess_server | Aggregated pre-flight trust assessment across all tools on an MCP server. Same verdict shape as check_tool_trust. Use for "is THIS server worth integrating?" decisions. v1 advisory; conformance monitored not enforced; verdicts may be UNVERIFIED if not yet probed. |
