## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to basitalisandhu/dev-mcp-servers).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 3 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 794 tokens (~198/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 86/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 57% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (4)

### `lint_openapi` (~189 tokens)

Lint an OpenAPI document

Check an OpenAPI 3.x document and return findings sorted by severity (error, warning, info), each with a rule id, a JSON Pointer path into the document and a message. Rules cover: openapi version, http server URLs, missing or unused security schemes, operations with no security requirement (and explicitly public ones), undefined schemes, operations without responses or without a success response, responses and parameters without descriptions, path parameters not declared or not required, missing operationId and duplicates, unversioned paths, request bodies without content, deprecated operations and undeclared tags. Pass ignore to silence rule ids.

Input parameters:

- `document`: The document itself, as JSON or YAML text or as an object. Alternative to path.
- `ignore` (array): Rule ids to skip.
- `path` (string): Path to a local OpenAPI JSON or YAML file (up to 5242880 bytes).

### `list_operations` (~151 tokens)

List the operations of an OpenAPI document

Return every operation (method and path) with operationId, summary, tags, deprecated flag, effective security (the operation's own requirement, the global one, 'public' for security: [], or 'inherited-none' when nothing applies), parameters with location and required flag, request body media types and response codes. Optional filters: tag, method, path_prefix.

Input parameters:

- `document`: The document itself, as JSON or YAML text or as an object. Alternative to path.
- `method` (string)
- `path` (string): Path to a local OpenAPI JSON or YAML file (up to 5242880 bytes).
- `path_prefix` (string)
- `tag` (string)

### `get_operation` (~137 tokens)

Get one operation

Return the full definition of one operation, selected by operation_id or by method and path, with path-level parameters merged in and local $ref values resolved one level. Useful for reading a single endpoint out of a large document.

Input parameters:

- `document`: The document itself, as JSON or YAML text or as an object. Alternative to path.
- `method` (string)
- `operation_id` (string)
- `operation_path` (string): Path template as written in the document, for example /users/{id}.
- `path` (string): Path to a local OpenAPI JSON or YAML file (up to 5242880 bytes).

### `explain_rule` (~133 tokens)

Explain a lint rule

Describe one lint rule: its default severity, what it detects and how to fix it. Rules: openapi-version, info-description, server-http, no-security-schemes, operation-no-security, operation-public, security-scheme-undefined, unused-security-scheme, operation-no-responses, operation-no-success-response, response-no-description, operation-no-description, operation-no-operation-id, duplicate-operation-id, path-unversioned, path-parameter-undefined, path-parameter-not-required, parameter-no-description, parameter-no-schema, request-body-no-content, deprecated-operation, tag-undefined.

Input parameters:

- `rule` (string, required)

## Common questions

### What is the OpenAPI Lint MCP server?

OpenAPI Lint is an MCP server listed in the public MCP registry as io.github.basitalisandhu/mcp-openapi-lint. Lint OpenAPI 3.x documents for missing security, responses, descriptions and versioning. This page covers its container image (ghcr.io/basitalisandhu/mcp-openapi-lint).

### Is the OpenAPI Lint MCP server safe to use?

OpenAPI Lint scores 49 out of 100 on VerifyMCP. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the OpenAPI Lint MCP server expose?

OpenAPI Lint exposes 4 tools: lint_openapi, list_operations, get_operation, explain_rule. Their descriptions and schemas cost roughly 610 tokens of context every time the server is loaded.

### Is the OpenAPI Lint MCP server still maintained?

OpenAPI Lint is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the OpenAPI Lint MCP server under?

OpenAPI Lint declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
