422 MCP servers and agent skills in the Developer Tools category, ranked by quality score.
Guardrail that checks agent-written code against a repo's own git-history-learned patterns — flags foreign dependencies, reinvented functions, misplaced code, broken layering, and gamed tests. Exposes `voice_context` (the repo's familiar imports/idioms for a file, so agents write in-voice before generating), `check` (score a generated hunk against the repo's patterns), and `explain`. 100% local, n
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`.
Justfile integration that enables LLMs to execute any CLI or script commands with parameters safely and easily, with environment variable support and comprehensive testing.
Log-stream tools for on-call / SRE agent workflows** — expose `rlg` (RustLogs) log files as MCP tools. Three tools: `tail_log` (last N events, filtered by level/target), `filter_log` (JSON-path-style predicates), `summarize_errors` (grouped error taxonomy). Speaks JSON-RPC 2.0 over stdio; near-lock-free structured logging engine underneath (65k-slot ring buffer, 14 output formats, `os_log`/`journa
Dependency intelligence for AI coding agents. Live CVE scanning, dependency health, upgrade planning, ecosystem news, and decision memory. 14 tools, zero config, privacy-first.
Agent-optimized MCP server replacing built-in file, search, exec, and git tools with compact structured JSON. Native plugins for git, cargo, gh, and docker. Semantic output filtering, read deduplication, batch operations, and token analytics. Benchmarked 20-45% token savings.
