EchelonGraph MCP Server

Official

Check a lockfile against the advisory corpus

scan_manifest
Read-onlyIdempotent

Check a project's lockfile or pinned manifest against EchelonGraph's advisory corpus, returning one vulnerability verdict per dependency.

Instructions

Check a project's lockfile or pinned manifest against EchelonGraph's advisory corpus, one verdict per dependency. Pass files: 1 to 20 of filename and content, up to 5,000,000 characters in all; the filename, or format, gives the format. Read: requirements.txt (== and === pins only), go.mod (require, after replace and exclude), package-lock.json and npm-shrinkwrap.json (v1 to v3), Cargo.lock, Gemfile.lock, composer.lock, poetry.lock and gradle.lockfile. package.json, pyproject.toml, Pipfile, Gemfile, Cargo.toml, composer.json and build.gradle hold ranges and are refused, naming the lockfile to pass; go.sum is refused: it lists versions the build does not select. This server reads the files into purls and only the purls are sent to the API, in POST bodies of at most 200, never in a URL; filenames and file contents are not sent on. Run from npm, this server is on your machine; over the hosted endpoint (mcp.echelongraph.io) it is EchelonGraph's, and the files are the request body, accepted up to 6 MiB. data.results holds one row per distinct purl, with verdict (affected, not_affected, undetermined or not_assessed), not_assessed_reason, cve_ids and matched_via; each match carries kev_listed, epss_score and fixed_in or null with fixed_in_reason. not_affected is the only clean verdict. data.not_checked lists each entry not sent, with file, line and reason: version_unpinned (a range), version_unresolved, local_path, vcs_source or unsupported_line; not_checked entries are not clean. At most 2,000 distinct purls per call, within 50 seconds; data.not_sent_purls lists any not sent, unchecked and not clean. Past 30,000 characters of JSON, the first text block holds data cut to fit, and the note says what the cut leaves out and where to read it (TEXT CUT); so is structured data (DATA CUT), unless full: true. Cut, each row keeps index, purl, verdict, not_assessed_reason and cve_ids at least; not_checked keeps its first 20.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
fullNotrue: data in the structured result is the answer whole, however long. Without it, a structured result past 30,000 characters of JSON has its data cut (DATA CUT): in an order the note states, the entries of its longest lists keep only some of their fields, and then the lists only some of their entries; data_truncated is true, and truncated gives each list cut with its total, the number returned and whether its entries are thinned. Whole data is for a program; a client that sizes structured results, as Claude Code does against MAX_MCP_OUTPUT_TOKENS, can refuse an answer past its cap.
filesYes1 to 20 files, up to 5,000,000 characters of content in all; read by this MCP server into purls, and only the purls are sent to the API; over the hosted endpoint (mcp.echelongraph.io) the files are the request body

  2. Addedv2.7.0

TDQS

A4.5/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations cover read-only/idempotent safety, but the description adds substantial non-obvious behavior: privacy disclosure that only purls are POSTed and filenames/contents are not sent, a 2,000-purl / 50-second cap, truncation semantics (TEXT CUT / DATA CUT with full: true escape), and the critical verdict rule that 'not_affected is the only clean verdict' and not_checked entries are not clean.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Purpose is front-loaded, but the body is a very long, densely packed run-on stream of facts (formats, privacy, limits, truncation) with several sentence-level redundancies against the schema's own field descriptions (file counts, hosted-endpoint note). Information-dense but hard to scan, so not concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given an output schema exists, return values needn't be restated, yet the description still covers the fields that matter for interpretation (verdict enum semantics, not_assessed_reason, fixed_in, not_sent_purls) plus limits, privacy and truncation. An agent has everything needed to call it correctly and read the result.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds meaning beyond the schema: it explains that filename picks the format unless format overrides, and spells out the operational consequence of full (whole vs. cut structured data and client cap behavior). It does not add much on content/filename fields themselves.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource ('Check a project's lockfile or pinned manifest against EchelonGraph's advisory corpus') and states the unit of output ('one verdict per dependency'). This clearly separates it from sibling tools like check_sbom and check_affected without the agent needing to open a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives concrete when-to-use guidance via accepted formats and explicit refusals (package.json, pyproject.toml, Pipfile etc. 'hold ranges and are refused, naming the lockfile to pass'; go.sum refused with a reason). It stops short of naming sibling tools as alternatives, so it is clear context rather than full alternative routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
