javats-impact-mcp
Read-only MCP server for cross-stack impact analysis across Java Spring Boot backend and TypeScript frontend linked through OpenAPI.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
index_projectBuild or refresh the cross-stack SQLite index that every other tool reads from. Scans the Java backend (tree-sitter), the TypeScript frontend (ts-morph), and the OpenAPI spec, then links them. Read-only against your source; it only writes the local index DB. Run this once at the start of a session, …
find_symbolLook up a symbol by exact name to obtain its `symbol_id`, file, and line. This is the entry point for the id-based tools (`find_references`, `analyze_impact`, `explain_symbol`). Returns every matching symbol across Java, TypeScript, and OpenAPI, so filter with `kind` when a name is ambiguous. Requir…
find_referencesList same-language references to a symbol (Java refs for a Java symbol, TS refs for a TS symbol). This is intra-stack only — for cross-stack (Java → OpenAPI → TypeScript) reach, use `analyze_impact` instead. Requires `index_project`.
get_endpointResolve one HTTP endpoint across the stack: the Java controller method, its OpenAPI operation, and the DTO schema (with fields) it returns. Use it to see the request/response contract of a route. Requires `index_project`.
analyze_impactCompute the cross-stack blast radius of changing a symbol — the headline tool. Walks Java → OpenAPI → TypeScript to find affected endpoints, TS call sites, and JPA/DB mappings, and returns a migration checklist. Every TS site carries a confidence flag: `high` (resolved via the TS type system or a ge…
get_git_contextSummarize git history for a file or symbol: recent commits, the authors who touched it, and a blame summary — useful for finding who to ask before changing code. Runs `git log`/`blame` only (no writes, no network). Requires `index_project` when passing a symbol name so it can be resolved to a file.
explain_symbolOne-shot overview of a symbol: its definition, same-language references, any linked endpoint, and git context, aggregated into a single summary. Use it for a quick orientation before deciding whether to run the deeper `analyze_impact`. Requires `index_project`.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
simple-git has blockUnsafeOperationsPlugin bypass via case-insensitive protocol.allow config key enables RCE
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
simple-git is vulnerable to Remote Code Execution
JAVATS_CONFIG"env": { "": "/absolute/path/to/javats-mcp.config.json" }Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — index_project (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_symbol (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_references (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Production dependencies are patched
1 critical, 5 high severity in production deps — simple-git@3.27.0 (critical), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
