AgentCanary (mrcerq/agentcanary-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.

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.

AC_API_BASEAC_API_KEY"env": { "": "ac_your_key_here" }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
19/19 tools missing one or more hints — get_briefs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_indicators (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_regime (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +16 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
Only 2/19 tool handlers declare input schemas (11%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
17/19 tool handlers wrap calls in try/catch (89%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets stay with their owner
3 secret/sensitive values flow into network calls (AC_API_KEY → dynamic, AC_API_KEY → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
