disvr
Tool search engine for AI agents. One API call to discover the best MCP server for any task. 900+ services indexed with 4-dimensional value ranking.
Warning. Serious findings were identified. Review the full report before connecting. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
discover_toolsFind the best tools for a task. Returns ranked recommendations with install instructions.
get_tool_detailsGet full details for a specific tool, including install instructions, required environment variables, and available tool functions.
report_resultReport the outcome of using a recommended tool. Helps improve future rankings.
list_toolsBrowse indexed tools. No authentication required.
get_failover_adviceGet advice on what to do when a tool call fails. Returns recommended action (retry, wait, switch tool) based on the error type and service health.
get_alternativesGet healthy alternatives for a degraded or dead tool. Returns empty if the tool is healthy.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
hono: CORS Middleware reflects any Origin with credentials when `origin` defaults to the wildcard
Hono: Path traversal in toSSG() allows writing files outside the output directory
Hono missing validation of cookie name on write path in setCookie()
Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths
Hono: Cookie helper does not sanitize sameSite and priority, allowing Set-Cookie injection
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
6/6 tools missing one or more hints — discover_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_tool_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); report_result (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
4/6 tools referenced in tests (67%)
Write tests that reference each tool by name so every tool has at least one test.
Readable source code
1 file are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
Production dependencies are patched
0 critical, 1 high severity in production deps — hono@4.12.9 (high), hono@4.12.9 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
