OpenAPI OperationId Linter & Fixer
OpenAPI OperationId Linter & Fixer: Lints operationId properties for casing conventions, duplicates, and missing values.
About this openapi operationid linter & fixer
OpenAPI OperationId Linter & Fixer — browser-based utility.
How this tool works
Checks seven lowercase HTTP method keys for missing or duplicate operationId values and can generate identifiers from method and path text. It does not enforce camelCase and does not recheck generated identifiers for collisions in the same pass.
- Contract Ingestion & Format Parsing: Reads OpenAPI YAML or JSON contracts, parsing the top-level info, servers, paths, and components blocks.
- Schema Dereferencing & Graph Resolution: Resolves internal and external $ref pointers using per-path visited sets to prevent false circular recursion alarms.
- Protocol Mapping & MCP Transformation: Maps HTTP operations, path parameters, and requestBodies into MCP tool declarations with JSON Schema input schemas.
- Validation & Export: Emits valid MCP manifests or client interfaces ready for Claude, Gemini, or ChatGPT integration.
Worked example
Scenario: An API SDK maintainer checks that all operations in an OpenAPI document define unique camelCase operationIds.
Sample input:
Processing: Lints operationId properties for casing conventions, duplicates, and missing values.
Illustrative output:
Limits and verification
Requires specifications to contain required OpenAPI root keys ('openapi', 'info', 'paths'). Handles deep schema recursion by truncating self-referential children with a safe guard marker. Flags invalid YAML indentation with line numbers.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
What does OpenAPI OperationId Linter inspect?+
It walks recognized HTTP operations in the supplied OpenAPI paths and reports missing or duplicate operationId values with their method and path.
What did the browser fixture check?+
A GET /pets operation without an operationId returned valid false, operationCount zero, and the explicit missing-operationId issue.
Can the page automatically generate missing IDs?+
The underlying implementation has a fix mode that builds IDs from a method and path, but the rendered page fixture exposes the linter mode; the Phase2 test covers that internal branch.
What does a clean report prove?+
It only shows that recognized operations had nonduplicate IDs in the supplied document. It does not generate an SDK, validate every OpenAPI rule, or publish a changed specification.
