credential-broker-mcp (SarutobiSasuke8/credential-broker-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
A local-first MCP server that lets AI agents use gated APIs without holding keys, enforcing declarative policies, injecting secrets server-side, and auditing access without content.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
minimatch ReDoS: nested *() extglobs generate catastrophically backtracking regular expressions
minimatch has a ReDoS via repeated wildcards with non-matching literal in pattern
minimatch has ReDoS: matchOne() combinatorial backtracking via multiple non-adjacent GLOBSTAR segments
BROKER_AGENT_IDresearcher npm startBROKER_AUDIT_FILEAudit log path. Default data/audit.jsonl.BROKER_POLICY_FILEPolicy path. Default config/broker.yaml.All four hints declared on every tool
4/4 tools missing one or more hints — broker_whoami (missing: openWorldHint); broker_list_credentials (missing: openWorldHint); broker_explain_request (missing: openWorldHint), +1 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 inputs are validated
2/4 tool handlers declare input schemas (50%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/4 tool handlers wrap calls in try/catch (25%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/4 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 3 high severity in production deps — minimatch@10.1.1 (high), minimatch@10.1.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
