422 MCP servers and agent skills in the Developer Tools category, ranked by quality score.
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.
Routes an AI coding agent's code search through an official language-server index (clangd / Roslyn / tsserver / pyright) instead of grep, returning a token-capped `file:line` list with no source bodies — ~20× fewer tokens. Also symbol-level edit-by-name, a Bash-grep→indexed-query rewrite hook, and git/p4 output compaction. Local-only, no IDE. Claude Code plugin + `vts` CLI.
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`.
MCP server that helps AI agents explore OpenAPI specs, search endpoints, and generate TypeScript types.
Offline access to TwitterAPI.io documentation for AI assistants. 52 API endpoints, guides, pricing info, and authentication docs.

Free tier, no key needed to start. Local stdio via `npx @pntr/cli` or hosted endpoint (`https://api.pntr.dev/mcp`, OAuth).
Deterministic axe-core accessibility scanning (WCAG 2.1 AA, EN 301 549, PDF/UA) through a [wcagc](https://wcagc.com) account: scan any public URL or PDF, crawl a whole registered site, replay saved multi-step journeys, and read violation trends. Returns structured findings — rule, severity counts and the success criteria involved — so the assistant reasons over real results rather than guessing fr

Log-stream tools for on-call / SRE agent workflows** — expose `rlg` (RustLogs) log files as MCP tools.
