What this MCP does

Scans MCP discovery metadata to identify tool-selection collisions and produces routing analysis reports.

Capabilities

Tools

3 tools
get_selection_report
Read and agent-enrich an existing public scan report by id; no new target request or model call.
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'get_selection_reportArguments', 'required': ['report_id'], 'properties': {'report_id': {'type': 'string', 'title': 'Report Id', 'pattern': '^[0-9a-f]{16}$'}}}
Output schema 
{'type': 'object', 'title': 'get_selection_reportDictOutput', 'additionalProperties': True}
scan_mcp_metadata
Create a free public report of MCP tool-description routing collisions. Reads discovery metadata (initialize/tools/list) only; never calls target business tools or spends funds. Use a public HTTP(S) URL without credentials, query or fragment. Results use at most 12 tools and 24 generated cases, not a real-model evaluation. The returned report is enriched with agent_plan candidate description-only edits and a machine-readable rerun instruction. Candidate edits are not untouched-holdout proof. Reports persist and are public by link. For an existing report use get_selection_report. Set internal_test=true for owner/CI validation so it is excluded from public scans. source is a self-reported referral bucket, not identity verification.
Open world
Input schema 
{'type': 'object', 'title': 'scan_mcp_metadataArguments', 'required': ['mcp_url'], 'properties': {'source': {'type': 'string', 'title': 'Source', 'default': 'other', 'maxLength': 32}, 'mcp_url': {'type': 'string', 'title': 'Mcp Url', 'maxLength': 2048, 'minLength': 8}, 'internal_test': {'type': 'boolean', 'title': 'Internal Test', 'default': False}}}
Output schema 
{'type': 'object', 'title': 'scan_mcp_metadataDictOutput', 'additionalProperties': True}
selection_lab_info
Get free service capabilities, limits, privacy and connection details; does not scan a target.
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'selection_lab_infoArguments', 'properties': {}}
Output schema 
{'type': 'object', 'title': 'selection_lab_infoDictOutput', 'additionalProperties': True}
