MCP Servers

Capstone of the Grand Line MCP set: a "collect them all" server that unlocks once the other tools are installed. pip install laugh-tale-mcp

MCP server that lets AI agents create and manage public tunnels to local services (webhooks, dev servers, sharing) — six tools covering HTTP/TCP/UDP tunnels, custom subdomains, regions, and load-balanced pools. Pairs with the rustunnel CLI; managed cloud or self-hosted (AGPL).

Type-faithful calculator: evaluate expressions under fixed-point, IEEE-754 double, or exact rational arithmetic, with every answer labelled exact vs inexact. Tools: calculate, analyze, solver, help, info. Offline, no network. uvx mcp-abacus.

Semantic code graph MCP server for AI coding agents. Indexes your codebase into a typed graph (functions/types/modules as nodes; CALLS/IMPORTS/DATAFLOW/EFFECTS as typed edges) and exposes 40+ tools for call-chain tracing, data-flow analysis, semantic search, and invariant checking — so agents navigate code structure instead of reading files line by line. npm install -g grafema

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

Read-only static scanner for MCP / agent-gateway production-readiness. The scangateway tool scores a repo across 7 security dimensions (RBAC, fail-closed, supply chain, observability, cost, secrets, prod-readiness). Never executes code or prints secret values.

MCP server for the VerifyAX platform. Enables agent evaluation, simulation testing, and functional/non-functional verification workflows through natural language.

The API-change deploy gate for AI coding agents: "is it safe to ship this API change to my consumers?" Analyze-only OpenAPI breaking-change detection + migration guides.

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

Design-system memory for coding agents with 46 MCP tools for UI audits, Tailwind token extraction, shadcn registry workflows, Figma context, design docs, and interface-quality diagnostics.

Drives the full App Store release cycle for iOS/macOS apps: version bump, archive + sign + TestFlight upload via your fastlane lane (as async jobs with log polling — the step REST-only ASC servers can't do), metadata updates, and review submission via the ASC API. Zero-dependency ES256 JWT auth. npx appstore-release-mcp

Visual feedback as agent work packets. Stakeholders drop pins on your live app; your AI coding agent reads each pin (selector, screenshot, DOM snippet, thread, acceptance criteria) via MCP and ships the fix, recording the commit/branch/PR on resolve. Install: npx pincushion-mcp.

Lets AI agents explore elaborated SystemVerilog/Verilog designs (RTL or gate-level netlists) without pasting RTL into context: trace signal fan-in/fan-out, walk module hierarchy, and jump to exact file:line source, backed by the najaeda netlist engine.

MCP server for microservices.sh: inspect verified Cloudflare-native modules/templates, generate app plans/projects, run checks, and trigger confirmation-gated preview deploys. Install via npx -y @microservices-sh/mcp.

100% local semantic code search for AI agents: AST-aware chunking (tree-sitter), hybrid BM25+dense retrieval, and a code knowledge graph (callers, inheritance, imports) over codebases, docs sites, and PDFs. Install via pipx install lynx-mcp.

Local-first MCP safety and verification layer for AI coding agents with workspace confinement, command allowlists, scope-violation detection, and auditable task evidence. Install: npx -y patchwarden@0.6.1.

🎖️ - Deploy and operate multi-user web apps from an agent: one call returns a live app on its own URL with magic-link sign-in, a shared realtime database, per-role permissions, email notifications and file uploads, and the agent keeps read and write access to the app's data afterwards to keep changing it. Remote https://homespun.dev/mcp or npx -y @homespunapps/mcp.

Multi-purpose API toolkit: email validation, DNS lookup, WHOIS, SSL certificate inspection, IBAN validation, business day calculator, hash encoding, and GPU pricing. Free tier included. pip install kiprio-mcp

Deterministic slop detector for AI-generated prose. Flags filler phrases and clichés with zero false positives by design (curated phrase list, not a model), returns exact spans plus a pinnable 0-1 score, and runs offline with no API key. CLI + CI exit code + MCP server for agents to self-check their own output before it lands in a PR or doc. pip install defluff

Local-first Project Telos MCP tool line for inspectable AI work: source intake, workspace context, routing ledgers, action receipts, and MATCH / DRIFT / UNVERIFIABLE verification packets across 5 stdio servers.

MCP Agent Health Reporter — advisory agent health scan under AOS discipline (manifest, services, immune loop, evidence). Stdio MCP: mcp-agent-health. Install: pip install mcp-agent-health==0.3.1 · PyPI

MCP Blast-Radius Auditor — static blast radius extraction and AOS manifest.json divergence gate (Oracle / Permitted / Prohibited). Stdio MCP (mcp-blast-radius) plus CI blocking gate (mcp-blast-radius-gate). Install: pip install mcp-blast-radius==0.2.0 · PyPI

Lets an AI agent gate its own work before claiming "done": a fail-closed ship checklist (verifygate counts a check satisfied only if explicitly proven), required independent refute-first review, and an append-only sha256-chained receipts ledger that makes any edit to past receipts detectable. pip install mcp-agent-gate.

Project-aware, read-only Nacos config & service-discovery server for Spring Cloud repos. Zero setup: auto-discovers every environment (dev/test/prod/...) from the repo's application/bootstrap files, with cross-environment key-level config diff. Single file, zero dependencies.
