Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

OpenAPI To MCP Skill
Use this to turn an API into a narrow, safe agent tool surface.
Workflow
- Prefer a local OpenAPI/Swagger spec file. If the spec must be fetched, record
the URL and do not send credentials.
- Run the read-only surface audit when a local spec is available:
``bash python3 plugins/codex-supercharge/scripts/openapi_surface_audit.py path/to/openapi.json ``
- Inspect auth, servers, paths, schemas, request bodies, response shapes, rate
limits, and write methods.
- Group endpoints into workflows, not raw endpoint dumps.
- Mark each operation:
- read-only
- write
- destructive
- admin
- credential-sensitive
- Generate a minimal MCP/tool plan or capability manifest.
- Create a Codex skill that teaches when and how to use the API.
- Add safety confirmations for write/destructive/admin operations.
Tool Plan Template
# API Tool Plan
## Auth
## Read Tools
## Write Tools
## Destructive Tools
## Admin And Credential-Sensitive Tools
## Rate Limits
## Error Handling
## Required Confirmations
## Example PromptsSkill Rule
The skill should describe business workflows, not every endpoint. Keep endpoint details in a reference file.

Skip When
- The API has no spec or stable docs to inspect.
- The user only needs a one-off HTTP call, not an agent/tool surface.
- The task is only MCP conformance/release gating; use
$auto-skill-build-mcp-conformance-harness.
Validation
- Auth, rate limits, write/destructive operations, and confirmations are explicit.
- Generated tool groups map to workflows rather than raw endpoint dumps.
- Credential-sensitive operations route through
$mcp-safety-review. openapi_surface_audit.pywas run or the reason it could not run is stated.
