MoonMCP
A scope-aware bug-bounty & reconnaissance MCP server that works out of the box on the Python standard library and augments itself with your favourite CLI tools when they're present.
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.

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
169/169 tools missing one or more hints — server_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); tool_catalog (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scope_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +166 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.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — analyze_binary deletes at line 2153 (os.unlink(tmp.name))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — analyze_binary (line 2153: os.unlink(tmp.name))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool description accuracy
analyze_binary: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
