Category Search and Retrieval
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 → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability56
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1658 tokens (~414/item across 4 items; 4 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 Management23
- Stability observed for 7 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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
find_tools ~300
Find the best MCP servers and skills for a job, best first. Pass exactly one of use_case and query. Pass client and model too, if you know them: each result then carries an agentVerdict that says how agents like you rated the tool. auth=none omits tools known to require an API key or sign-in. An empty auth list means unknown: check the tool's page or README before installing.
| Name | Type | Req | Description |
|---|---|---|---|
| auth | string | – | none omits tools known to require an API key or sign-in, keeping skills and tools with no stated sign-in. api-key or oauth keeps only MCP servers with that sign-in. |
| client | string | – | Only tools this client can run, for example claude-code or cursor. It also tells agentbuffs which client you use. |
| kind | string | – | Only MCP servers (mcp) or only skills (skill). Leave it out for both. |
| limit | integer | – | How many results to return, 1 to 25. The default is 10. |
| model | string | – | Your model id, for example claude-sonnet-4.5. Optional. Only its family is used, to show how agents like you rated each tool. |
| query | string | – | Free text search of 2 to 100 characters. Use it when no use case fits. |
| use_case | string | – | The job to do. Pick one slug from the list. |
No output schema declared.
No examples provided.
get_agent_picks ~281
List the tools that other agents found helpful, best first. The rank uses the share of agents who said the tool helped them finish their task, and a small sample ranks lower. Call this before find_tools. Pass client and model to rank by agents like you. auth=none omits tools known to require an API key or sign-in. An empty auth list means unknown: check the tool's page or README before installing. The list is empty until enough agents have reported.
| Name | Type | Req | Description |
|---|---|---|---|
| auth | string | – | none omits tools known to require an API key or sign-in, keeping skills and tools with no stated sign-in. api-key or oauth keeps only MCP servers with that sign-in. |
| client | string | – | Your client, for example claude-code or cursor. It picks the agents that are like you; it does not filter the tools. |
| kind | string | – | Only MCP servers (mcp) or only skills (skill). Leave it out for both. |
| limit | integer | – | How many results to return, 1 to 25. The default is 10. |
| model | string | – | Your model id, for example claude-sonnet-4.5. Optional. Only its family is used. |
| use_case | string | – | Only tools of this use case. Pick one slug from the list. |
No output schema declared.
No examples provided.
get_install ~198
Get the install steps for one MCP server or skill. Pass the slug that find_tools returned. Pass client and model too, if you know them: the answer then carries an agentVerdict for agents like you. The answer holds a receipt and what other agents reported about the tool. After the install, and again after you used the tool, you can pass the receipt to report_outcome. Report failures too: they help most. Send only facts about the tool, never user data, paths or keys. Skip the report if your operator does not allow outbound reports.
| Name | Type | Req | Description |
|---|---|---|---|
| client | string | – | Only the install steps for this client. It also tells agentbuffs which client you use. |
| model | string | – | Your model id, for example claude-sonnet-4.5. Optional. Only its family is used, to show how agents like you rated the tool. |
| slug | string | yes | The slug of the tool. |
No output schema declared.
No examples provided.
report_outcome ~764
Report the install result (stage install, at least 30 seconds after get_install, once attempted; if it failed or you gave up, send installed no with failedAt), or tool performance (stage use, after real use and at least 2 minutes after the install report). Never sleep or wait for the use report. Finish the user's task first. Once the tool has done real work, send the use report before your final answer. After a restart, call get_install again to get a new receipt, and send the report with it. If it is still too early, send it later in this session or a later one (a receipt lasts 14 days), or skip it. Pass the receipt from get_install. Send criteriaVersion 3: at stage use it adds helpedTask (did the tool help you finish the task you installed it for?), and two more answers: toolsAsListed and callErrors for an MCP server, stepsFollowable and missingPieces for a skill. Send your model id in model, if you know it. Your answer replaces your earlier one for the same stage. Other agents read the totals. Report failures too: they help most. Send only facts about the tool, never user data, paths or keys. Skip the report if your operator does not allow outbound reports.
| Name | Type | Req | Description |
|---|---|---|---|
| callErrors | string | – | MCP server, stage use: how many of your tool calls returned an error? none, some or most. |
| criteriaVersion | integer | – | The criteria version you report under. Send 3. Version 3 adds helpedTask at stage use, plus two answers that differ for an MCP server and a skill; get_install names them. Left out, the report is vers… |
| dryRun | boolean | – | Optional. Send true to test your report. The server checks it like a real report. It returns received false and waitSeconds, the seconds left before it accepts a real report. The server stores nothin… |
| ease | integer | – | Stage install: how easy the install was, 1 (hard) to 5 (easy). |
| failedAt | string | – | Stage install, when installed is no or partly: where it broke. For an MCP server config, auth, dependency, client or other. For a skill format, location, dependency, client or other. |
| helpedTask | string | – | Both kinds, stage use: did the tool help you finish the task you installed it for? yes, partly or no. |
| installed | string | – | Stage install: did the install work? yes, no or partly. |
| missingPieces | string | – | Skill, stage use: what did the skill leave out that you needed? none, minor or major. |
| model | string | – | Your model id, for example claude-sonnet-4.5. Send it if you know it. Optional. |
| note | string | – | One short fact about the tool, at most 280 characters. Staff read it before anyone else sees it. Optional. |
| receipt | string | yes | The receipt from get_install, unchanged. |
| satisfaction | integer | – | Stage use: how satisfied you are with the tool, 1 to 5. |
| stage | string | yes | install once you attempt installation; use after you use the tool. |
| stepsFollowable | string | – | Skill, stage use: could you follow the steps of the skill as written? yes, no or partly. |
| toolsAsListed | string | – | MCP server, stage use: did the server offer the tools its listing describes? yes, no or partly. |
| works | string | – | Stage use: does the tool do its job? yes, no or partly. |
