422 MCP servers and agent skills in the Developer Tools category, ranked by quality score.
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).
Semantic code indexer with GraphRAG knowledge graph. Index your codebase, search in natural language, and expose everything via MCP so AI agents understand architecture — not just files.
High-performance, token-efficient spreadsheet analysis/editing (xlsx/xlsm) with region detection, structured reads, formula/style inspection, forking mechanics, and recalculation. Cross-platform.
Local repo-intelligence index and MCP server for coding agents — "what a repository knows about itself." Hybrid BM25 + vector semantic search, a tree-sitter code graph (callers/callees/imports across Rust, TS/TSX, Kotlin, C/C++, Python) with an optional compiler-grade SCIP oracle, queryable git/GitHub history, and typed, source-anchored repo memories (Invariant, Decision, Risk, …) that persist acr
MCP server for Atlassian Jira and Confluence with schema-validated Markdown↔ADF conversion. Catches content-model violations at conversion time rather than silently dropping ADF-only nodes like panels, mentions, and layouts.
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`.
Provides up-to-date documentation context for a specific Rust crate to LLMs via an MCP tool, using semantic search (embeddings) and LLM summarization.
Justfile integration that enables LLMs to execute any CLI or script commands with parameters safely and easily, with environment variable support and comprehensive testing.
MCP server for [Perfetto](https://perfetto.dev) trace analysis. Runs PerfettoSQL queries on `.perfetto-trace` / `.pftrace` files via auto-downloaded `trace_processor_shell`, with dedicated Chrome tools for page loads, scroll jank, main-thread hotspots, and stdlib module discovery. Cross-client tested on Claude Code and Codex. Available via `cargo install`, Homebrew tap, and curl install script.
Dependency intelligence for AI coding agents. Live CVE scanning, dependency health, upgrade planning, ecosystem news, and decision memory. 14 tools, zero config, privacy-first.
Semantic code index that extracts domain concepts, naming conventions, and behavioral similarity from codebases. One tool call instead of 19, ~20x fewer tokens for codebase understanding queries.
CLI-first API testing tool with structured JSON failures (`failure_category`, `error_code`, `hints`) so AI agents can branch on the taxonomy without parsing stderr. MCP tools: `tarn_run`, `tarn_validate`, `tarn_fix_plan`, `tarn_inspect`, `tarn_rerun_failed`, and more. Tests are `.tarn.yaml`. Single static binary (musl), MIT.
AI-powered time-travel debugger with bidirectional execution replay, audit-compliant hash-chain logging, and SIMD-accelerated stack unwinding. Free Hobby tier available.
A Model Context Protocol (MCP) server that integrates with SonarQube to provide AI assistants with access to code quality metrics, issues, and quality gate statuses
Outputs short-form Rust crate derived traits,interfaces, etc. from AST (uses same api as rust-analyzer), output limits (token estimation) & crate docs w/regex stripping.
