Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1136 tokens (~162/item across 7 items; 7 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 Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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.
compare ~103
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slugs | array | yes | Array of 2-5 server slugs to compare. |
No output schema declared.
No examples provided.
creator_profile ~121
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.
| Name | Type | Req | Description |
|---|---|---|---|
| creator | string | yes | Creator display name (case-insensitive) OR GitHub username. From a search_servers result, use the `creator` field. |
No output schema declared.
No examples provided.
get_server ~128
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.
| Name | Type | Req | Description |
|---|---|---|---|
| slug | string | yes | Server slug (from search_servers results or the URL: mcp-marketplace.io/server/{slug}). |
No output schema declared.
No examples provided.
list_categories ~41
List all MCP Marketplace categories with slug, name, description, and approved server count. Use the returned `slug` as the `category` filter in search_servers.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
recently_added ~125
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.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | — | Only include servers created within the last N days (1-365). Omit for no date bound. |
| free_only | boolean | — | If true, exclude paid servers. |
| limit | integer | — | Max servers to return (1-25). Default 10. |
No output schema declared.
No examples provided.
search_servers ~356
Search the MCP Marketplace catalog. With a free-text `query` and default `sort`, results are ranked by semantic similarity (gte-small embeddings + cosine similarity), so natural-language queries like 'manage my calendar', 'something to read PDFs', or 'database for my agent' work as well as keyword searches. 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.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | — | Category slug filter. Call list_categories to see valid slugs. |
| free_only | boolean | — | If true, exclude paid servers. |
| limit | integer | — | Max results per page (1-25). Default 10. |
| page | integer | — | 1-indexed page number. Combine with `limit` to paginate past the first window. Defaults to 1. |
| query | string | — | Free-text search across name, tagline, description, tags, and MCP tool names. |
| sort | string | — | Ranking order. Defaults to 'relevance' when query is set, else 'installs'. |
| transport | string | — | Filter by transport. 'stdio' = local (npm/pip); 'streamable-http' = hosted remote. SSE is not exposed because the catalog doesn't distinguish SSE from streamable-HTTP and filtering on it would always… |

No examples provided.
similar_to ~178
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.
| Name | Type | Req | Description |
|---|---|---|---|
| free_only | boolean | — | If true, exclude paid servers from the comparison set. |
| limit | integer | — | Max similar servers to return (1-10). Default 5. |
| slug | string | yes | Reference server slug (the one you want similar alternatives to). |
No output schema declared.
