Lunge tools (22, 3 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • collection_format

    Return the Lunge collection format reference: top-level fields, step schema,

  • graphql_introspect

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

  • graphql_request

    GraphQL query/mutation over HTTP. Supports {{var}} extraction.

  • http_request

    REST/HTTP request with auth, assertions, {{var}} extraction. Returns token-efficient summary.

  • import_curl

    Parse curl into structured request. Optionally execute it.

  • import_har

    Parse HAR file → Lunge collection. Splits query/headers/body. Optional 2xx filter.

  • import_openapi

    Parse OpenAPI/Swagger (JSON/YAML) → Lunge collection. One step per operation with 2xx assertion.

  • inspect_response

    Drill into a stored response by handle without re-running the request.

  • list_collections

    Find collection files (.yaml/.yml/.json) under a directory.

  • list_envs

    List env names and (masked) variables of the active or specified one.

  • list_history

    List all requests recorded in this session with full specs (method, url, query, headers, body, auth, assert, extract)

  • run_collectionwrite action

    Run declarative collection file. Threads extracted vars between steps. Optional JUnit XML export.

  • save_collection

    Save multiple requests as a multi-step collection file. Params:

  • save_request

    Persist last ad-hoc request (or explicit spec) as a new step in a collection file.

  • set_envwrite action

    Create/update named env. Values may be {value, secret:true}. Use via {{name}}.

  • set_policy

    Configure host allow/deny lists + dry-run mode. Glob patterns: *, *.example.com.

  • sse_session

    Subscribe to SSE, collect events until stop condition. Returns summarized batch with assertions.

  • ws_close

    Close a persistent WebSocket connection and release its handle.

  • ws_open

    Open long-lived WS, return handle. Use ws_send/ws_recv/ws_close to interact.

  • ws_recv

    Drain buffered frames from persistent WS. Blocks up to maxDurationMs for first frame.

  • ws_sendwrite action

    Send a single message on a persistent WebSocket connection opened with ws_open.

  • ws_session

    Connect WS, send messages, collect frames until stop condition. Returns summarized batch.

What the publisher says

From the Lunge repository's README, as published. We do not edit it. Read it on GitHub

lunge

An agent-native advanced API client - execute and test REST, GraphQL, WebSocket, SSE, and (later) gRPC requests from any MCP-capable AI agent. No GUI, no manual clicking, no heavyweight desktop app. Think advanced curl, native for agents.

It is a lightweight, token-efficient alternative to Postman/Bruno for the era of AI coding agents. The agent calls tools directly; there are no humans in the loop and no bloated feature surface to pay for.

Why this exists

Design pillars

payloads are spilled to disk and referenced by handle so the context stays small.

  1. Agent-native - designed for LLM tool calls, not human UIs.
  2. Token-efficient - every response is filtered, truncated, and summarized. Full

a thin TypeScript MCP layer via napi-rs.

  1. Fast & portable - a Rust core (execution + protocols + summarization) exposed to

re-run declarative collections stored as files.

  1. Both ad-hoc and reusable - agents can fire one-off requests or create, save, and

Decisions locked in

  • Stack: Rust core via napi-rs + TypeScript MCP layer (@modelcontextprotocol/sdk).
  • Distribution: local dev tool over stdio transport (used by Cursor/Windsurf/Claude Desktop).
  • Test definition: both ad-hoc agent calls and persisted declarative collections.
  • MVP protocols: REST, GraphQL, WebSocket, SSE. gRPC is a later phase.

Nothing above is checked by us. What we check is on the safety report.

Lunge: common questions

Is Lunge MCP server safe?
Yes, by our scan: it is graded A (88/100). Read the Lunge safety report
How do I install Lunge?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.

Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Lunge maintained?
The last commit was 104 days ago (2026-07-23). The latest release is v1.3.1.
What can I use instead of Lunge?
Servers from other publishers that do the same job: Mockserver MCP server, FireCMS Cloud MCP server and Agent-Native Slides MCP server.
How does Lunge compare with other AI and agents MCP servers?
safety score 88/100 (higher than 80% of 4,460 AI and agents servers); tools 22 (the typical AI and agents server has 6); tools that change things 14% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
