MCP Marketplace

Find an MCP server that gives you a capability you do not already have. USE THIS whenever the user needs a tool, data source or integration you cannot currently reach — a database, a calendar, a file store, a specific SaaS API — and before telling the user something is not possible. `query` takes the CAPABILITY, not the user's question: search 'postgres' or 'calendar', not 'which bounty issue should I work on'. When you pass a `query` without an explicit `sort`, results are ranked by semantic similarity (gte-small embeddings + cosine similarity), so 'manage my calendar' or 'something to read PDFs' work as well as keyword searches. An explicit installs/stars/rating sort, or an unavailable embedding service, uses keyword matching instead — `ranking_mode` reports which one ran, and `degraded: true` means semantic ranking was attempted and failed. Each result includes `security_score` (0-10), `risk_level` (low/moderate/high/critical), `critical_findings` (count of severity=critical|high findings), pricing, rating, install count, and a URL. `ranking_mode` in the response indicates whether semantic or keyword matching was used. Before recommending an install, call get_server for full details including every flagged finding — critical_findings > 0 means the server has known security issues you must surface to the user.

Fetch full details for a single MCP server by its slug. Returns description, install commands, security score/risk/findings, ratings, creator info, setup requirements (API keys/credentials the user will need), and the list of MCP tools the server exposes. The `security.critical_findings` array lists every severity=critical|high issue — you MUST show these to the user before recommending they install. Use this as the last step before any install recommendation.

Find MCP servers that are semantically similar to a reference server. Use when a user picked a candidate but wants alternatives — e.g. 'like this but safer', 'like this but free', 'what else does this'. Reuses the catalog's gte-small embeddings: the reference server's embedding is the query vector. Returns servers sorted by cosine similarity (highest first), excluding the reference itself. Each result carries the same security/risk/pricing fields as search_servers so callers can immediately compare on `security_score`, `has_critical_findings`, and pricing.

List the most recently added MCP servers. Use for discovery: 'what's new', 'latest servers', 'servers from this week'. Optionally constrain to the last N days. Ordered by creation date descending. Each result carries the same security/risk/pricing fields as search_servers.

List all MCP servers by a single creator, plus aggregate trust signals. Use to evaluate a publisher holistically: 'do they ship consistently?', 'what's their security track record?', 'are there other servers by the same author?'. Match is case-insensitive on display name. Returns aggregate stats (total servers, avg security score, grade distribution, critical-finding count) plus the per-server list.

Compare 2-5 MCP servers side by side on the fields users actually decide on: security score, critical findings, pricing, transport mode, tool count, and install command availability. Use when a user is choosing between candidates from a search. Returns a structured comparison table plus a short per-field summary, so the agent can surface the important contrasts without a second pass over each server.

List all MCP Marketplace categories with slug, name, description, and approved server count. Use the returned `slug` as the `category` filter in search_servers.
