Trust breakdown (6 categories)

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. How we score →

Supply Chain Security88
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (104 of 108), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass

Provenance & Transparency45
Schema Quality & AI Usability71
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 2743 tokens (~124/item across 22 items; 22 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage90
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 69% of tool parameters carry a description.Partial
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 22 exposed · ~2,743 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
collection_format ~84

Return the Lunge collection format reference: top-level fields, step schema, request specs per protocol (http/graphql/ws/sse), full assertion vocabulary (status/header/jsonpath/timeMs/schema/not + matchers), WS/SSE-specific assertions, variable chaining (extract + {{var}}), and JSONPath syntax. Call this BEFORE writing explicit steps for save_collection or reviewing saved output.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

graphql_introspect ~73

Introspect GraphQL endpoint, return summarized schema with field signatures (args + return types) and input types.

NameTypeReqDescription

No output schema declared.

No examples provided.

graphql_request ~213

GraphQL query/mutation over HTTP. Supports {{var}} extraction. Note: `ok` reflects HTTP status only (200 = ok). GraphQL-level errors are returned in `graphqlErrors` — always check both. Use extract with $.data.* for success data and $.errors.* for error details.

NameTypeReqDescription

import_har ~166

Parse HAR file → Lunge collection. Splits query/headers/body. Optional 2xx filter. Params: path (required, .json HAR file), out (optional, write to .json/.yaml/.yml), only2xx (optional, only keep 2xx responses), maxSteps (optional, cap step count, default 200). Returns {ok, imported, name, steps, writtenTo}.

NameTypeReqDescription
maxStepsintegerCap the number of generated steps (default 200).
only2xxbooleanOnly include requests that returned a 2xx response.
outstringWrite the resulting collection to this path (.yaml/.yml/.json).
pathstringyesPath to the HAR file (.json).

No output schema declared.

No examples provided.

import_openapi ~165

Parse OpenAPI/Swagger (JSON/YAML) → Lunge collection. One step per operation with 2xx assertion. Params: path (required, file path), out (optional, write collection to .json/.yaml/.yml), includeTags (optional, only ops with these tags), maxSteps (optional, cap step count, default 200). Returns {ok, imported, name, steps, writtenTo}.

NameTypeReqDescription
includeTagsarrayOnly import operations with any of these tags.
maxStepsintegerCap the number of generated steps (default 200).
outstringWrite the resulting collection to this path (.yaml/.yml/.json).
pathstringyesPath to the OpenAPI/Swagger file.

No output schema declared.

No examples provided.

inspect_response ~220

Drill into a stored response by handle without re-running the request. Use jsonpath to pull only the slice you need. Supports RFC 9535 filters ($.items[[email protected]==1]) and slices ($.items[0:5]). Use double quotes in filters. Omit jsonpath to return the full stored body — for graphql_introspect this is the enriched `schema` (so $.queries, $.mutations, $.inputTypes work directly); for ws_session it's the `frames` array; for sse_session it's the `events` array; otherwise it's the parsed bodyJson/bodyText.

NameTypeReqDescription
handlestringyesresponseHandle from a prior tool call.
jsonpathstringRFC 9535 JSONPath. Filters need double quotes: [[email protected]=="x"]. Omit for full body.

No output schema declared.

No examples provided.

No output schema declared.

No examples provided.

list_history ~98

List all requests recorded in this session with full specs (method, url, query, headers, body, auth, assert, extract) and extracted values. Use this to review what happened before saving a multi-step collection. Each entry has an id (req_1, req_2, ...) for use with save_collection. Returns {count, entries:[{id, type, request, assert, extract, extractedValues, responseHandle}]}.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

save_collection ~269

Save multiple requests as a multi-step collection file. Params: path (required, .json/.yaml/.yml), fromHistory (optional, array of history ids from list_history — saves in specified order; omit to save ALL history), steps (optional, explicit step specs — overrides fromHistory; call collection_format first for the schema), name (optional, collection name), description (optional), vars (optional), defaults (optional). Steps preserve extraction chaining ({{var}} from earlier steps' extract). Returns {saved, path, stepCount, stepIds}.

Params: path (required, .json/.yaml/.yml), id (optional, step id), type (optional, http|graphql|ws|sse), request (optional, explicit spec; defaults to last call's request), assert, extract, tags, name (optional, set collection name). Returns {saved, path, stepId, stepCount} or isError if no prior request and no explicit request.

NameTypeReqDescription
