trailofbits/differential-review
Security-focused diff review with git history analysis
srbsa/diffgate
Deterministic guardrail for AI-written diffs, runnable from inside the coding agent's own loop over MCP. Zero-LLM-token, AST-precise rules (SQLi, SSRF, XXE, permissive CORS, prototype pollution, hardcoded secrets) across 8 languages, plus structural checks for reinvented helpers and over-abstraction — findings scoped to only the changed lines, same input always gives the same output, no false-bloc
nikolay-e/diffctx
Selects the minimum code context an LLM needs to understand a git diff: graph-based fragment selection under a token budget, deterministic, 30+ languages. Published on PyPI and in the MCP Registry.
corralimited/snapdiff-mcp
Intent-aware visual verification for coding agents: the agent declares what a UI change should affect, and SnapDiff diffs the page against a baseline and flags anything that changed outside that intent for review or rollback — local screenshot capture via Playwright.
mcurmi05/vdiff
Breaking-change diffs for npm packages so coding agents stop writing code against outdated API knowledge.
DigiCatalyst-Systems/dep-diff-mcp
Translates a lockfile diff (npm, PyPI) into a human-readable upgrade plan. Point it at a Dependabot PR and get back semver classification, breaking changes from GitHub release notes, CVEs fixed in range, migration links, and a per-package recommendation. Bulk tool ranks up to 50 changes by risk (security > caution > review > likely-safe > safe). Install via `npx -y @digicatalyst/dep-diff-mcp`.
gorosun/unified-diff-mcp
Generate and visualize unified diff comparisons with beautiful HTML/PNG output, supporting side-by-side and line-by-line views for filesystem dry-run integration

An MCP server that bridges to multiple OpenAI-compatible LLMs - your AI rubber duck debugging panel for explaining problems to various AI "ducks" and getting different perspectives
kage-core/Kage
Verified, git-native memory for coding agents. Memory is plain JSON packets committed in your repo, each checked against the code it cites — hallucinated citations rejected at write, stale or changed memory withheld at recall, plus diff-time stale-catch. Local-only (BM25 + vectors), no account, no API key. `npx -y @kage-core/kage-graph-mcp install`
delimit-ai/delimit
API governance server that detects breaking changes in OpenAPI specs. Diffs two spec versions, applies configurable policy rules (strict/default/relaxed), and returns structured pass/fail verdicts. 23 change types, 10 breaking. Supports OpenAPI 3.0, 3.1, and Swagger 2.0.
masondelan/selvedge
Change tracking for AI-era codebases. AI agents call it to log structured change events (entity + diff + reasoning) before the session ends, then query history with diff, blame, history, changeset, and search. Captures the intent that would otherwise evaporate.
graphpilot-oss/graphpilot
Structural memory for coding agents. Indexes TypeScript/JavaScript repos and exposes callers, callees, blast-radius impact, and symbol locations over MCP — with file:line@sha evidence anchors and branch-aware differential impact — so agents answer "who calls X?" / "what breaks if I change X?" without re-reading files. Local-only, zero telemetry, Apache-2.0. `npx @graphpilot-oss/graphpilot mcp`
liveblocks/liveblocks-mcp-server
Create, modify, and delete different aspects of [Liveblocks](https://liveblocks.io) such as rooms, threads, comments, notifications, and more. Additionally, it has read access to Storage and Yjs.
LeonTing1010/tap
MCP server that compiles AI browser automation into deterministic `.tap.json` plans (25-op closed union, zero runtime LLM), runs on your logged-in Chrome, and detects drift via semantic fingerprint diff when sites change. 65+ open community taps on 40+ sites.
richer-richard/cochlea
Render, analyze, and verify audio (WAV or FLAC) through a fully offline, deterministic engine. Compose scores as data, render byte-identical PCM, pull loudness, pitch, tempo, key, and structure reports, generate spectrograms, and diff two renders against each other. No ffmpeg, no audio device, just numbers an agent can actually reason about. `cargo install cochlea-mcp`
raveenb/fal-mcp-server
Generate AI images, videos, and music using Fal.ai models (FLUX, Stable Diffusion, MusicGen) directly in Claude Desktop
j0hanz/filesystem-context-mcp-server
Read-only MCP server for secure filesystem exploration, searching, and analysis with symlink protection.
fixed-width/glass
Gives a coding agent a build → see → interact → debug loop over the native GUI app it is writing: launch the app, screenshot it, read its accessibility tree, inject mouse/keyboard/gestures, tail its logs, and diff frames to confirm a change landed. Drives apps as an external black box with no app integration, so any toolkit or language works. 30 tools with text-first responses (element ids, diffs,
richer-richard/fenestra
Render and verify native Rust GUIs with no display or GPU: render to a typed accessibility tree, query/interact by semantic selector (never coordinates), check contrast/focus-order/hit-target-size, diff screenshots, and watch motion play as a captioned filmstrip. 13 tools. `cargo install fenestra-mcp`.
rwnalds/engram
Second brain your agents read and write, over a git-backed markdown vault. Authority-aware search ranks superseded and archived notes below live ones (from frontmatter, no vector DB), so agents quote the current doc, not the dead one. Per-agent read-only or write tokens, a git audit trail of every change with diffs, a knowledge-graph dashboard, and Obsidian compatibility.
dugubuyan/agent-nexus
Service-boundary-aware document exchange center for coordinating heterogeneous LLM code agents. Versioned Markdown store, pub-sub notifications, diff-aware updates, and lifecycle stage tracking. Each service registers as a sub-project; agents subscribe to cross-service document changes and receive structured diffs via MCP.
soren-achebe/backscroll
Answers "what did that command print?" from your real terminal history: a per-command PTY session recorder (OSC 133) stores every command's full output, exit code, cwd, and duration in local SQLite/FTS5, and the MCP server searches, retrieves, and diffs those outputs — secret redaction on by default before anything reaches the model.
djerok/glm-mcp
Run GLM (Zhipu/Z.ai) as a real sub-agent inside Claude Code or GitHub Copilot. GLM gets its own agent loop (read/write/edit/run) on your repo — not a single LLM call — with peak-aware Opus-vs-GLM routing, diff/dry-run/git-revert oversight, and a usage ledger. ~10x cheaper than Opus. Requires a Z.ai GLM Coding Plan key.
arnavranjan005/mcp-telemetry
Socket.IO-style telemetry for MCP servers. Instrument a tool call with a few lines of `mcp-telemetry-sdk`, and `telemetry_subscribe` streams its live progress (steps, logs, cost, done) to any connected MCP client via `notifications/progress` — no polling, and a job started in one session can be watched from a completely different one.
croc100/Litescope
MCP-first operations toolchain for SQLite, Cloudflare D1, and Turso. Inspect, diff, migrate, monitor, back up, and repair databases over stdio. Read-only by default; writes are opt-in, dry-run first, and auto-snapshot before applying. `npx -y litescope mcp`
seldonframe/reelier
Record an agent's tool-call workflow once, replay it deterministically at 0 tokens, and diff runs to catch drift — CI + snapshot tests for MCP tool-call workflows. `npx -y reelier serve`
AIDataNordic/Food-Recipe-MCP
Semantic search across 50,000+ Food.com recipes with hybrid dense+sparse retrieval and cross-encoder reranking. Filter by diet, cooking time and difficulty. Live remote endpoint available.
realkimbarrett/headline-matrix
Generate high-performing headline variations across different angles
xChuCx/agent-memory
Git-native project memory for coding agents: Markdown source of truth committed to your repo, reviewable staged updates (`review --diff` → `apply`), secret/PII-safe, branch-aware — no cloud, no vector DB.
