GitHub access for agents should come from GitHub itself, and this server earns that with toolsets, read-only mode and a frank account of what lockdown cannot do.
Best for: Developers and platform teams who want agents working on GitHub issues, pull requests and CI with scoped credentials.
Price: Free and MIT-licensed, hosted or self-run, on any GitHub plan. Tools for paid features (Copilot coding agent, some security alerts) need those licences.

Cheap insurance against invented APIs, provided you remember that every answer comes from a closed, community-fed index your agent will trust without question.
Best for: Developers using AI coding agents with fast-moving libraries such as Next.js, Supabase or Tailwind.
Price: Free: 1,000 calls a month, then 20 bonus calls a day. Pro: $10/seat/month with 2,000 calls per seat, then $5 per 1,000. Enterprise custom (small teams $30/user/month).

Twelve finished checks for the work coding agents skip, at a price measured in thousandths of a cent, built by someone who clearly expects the model to be wrong sometimes.
Best for: Developers who want a coding agent to screen fetched content, verify claims and review its own diffs cheaply before calling a task done.
Price: The server is free (MIT). Jev calls are billed by your provider: TypeSafe charges $42 per billion input tokens ($0.042 per million) with output tokens free, and the README says OpenRouter charges the same.

A model can be talked out of a finding; a failed CI check can't, and Semgrep lets you run the same check in both places.
Best for: Any team that wants AI-written code to face the same static-analysis gate as human code.
Price: Community Edition free under LGPL 2.1; Semgrep AppSec Platform (Pro rules, cross-file analysis, Supply Chain, Secrets) is paid.

If your errors already land in Sentry, this is the shortest path from a stack trace to a fix, and the project-scoped URL keeps the agent from wandering.
Best for: Teams that use Sentry and want coding agents to read real error and trace data while fixing bugs.
Price: The MCP server is free. Sentry has a free Developer plan for one user; Team is $26/month and Business $80/month billed annually; Seer costs $40 per active contributor per month on Team or Business.

Typed decisions that never leave your hardware and cost nothing per call, from a model its own authors say needs fine-tuning before you trust it.
Best for: Teams with labelled examples and data that must stay on their own hardware who want fast routing, triage or guard decisions inside an agent.
Price: Free and open source (Apache 2.0, code and weights). You pay only for the hardware it runs on.

Serena’s symbol-level tools are a real upgrade for agents in big codebases, but its trust-the-repository security model means untrusted code belongs in a container.
Best for: Developers running coding agents on large, typed or multi-language codebases they trust, who want reliable cross-file navigation and renames.
Price: Free and open source (GPL-3.0-or-later; the SolidLSP part is MIT). The optional JetBrains plugin is paid, with a 7-day free trial; price is set on the JetBrains Marketplace.

Still the cleanest way to hand a chat app one folder and nothing more, provided you remember the MCP project itself calls it a teaching example.
Best for: Users of Claude Desktop or custom agents who need controlled access to one or two local folders.
Price: Free and open source.

GhidraMCP gives a model the reverse engineer's core moves and saves its conclusions into the project, with 30 tools where its biggest fork ships 209.
Best for: Malware analysts and reverse engineers who want an assistant to triage and annotate binaries in Ghidra.
Price: Free and open source (Apache 2.0). Ghidra itself is free.

Semantic code search for agents that costs two tool definitions and no API keys; its striking benchmark figures are still the authors' own.
Best for: Developers who want their coding agent to find relevant code quickly without sending code to a cloud embedding service.
Price: Free and open source (MIT). No API keys or paid services needed.

A thin, careful connector that returns any System One model's probabilities untouched and leaves the hard part, writing good questions, to the agent.
Best for: Developers who want raw, typed decisions in their agent and may switch between hosted Jev and a self-hosted open model.
Price: The connector is free (MIT). Model calls are billed by the provider you choose; TypeSafe lists Jev at $42 per billion input tokens. Self-hosted Laya or CLM cost only your hardware.

Precomputed blast radius makes AI review cheaper on big repositories, and the project is unusually frank about where its numbers fall short; trim its 30 tools before installing.
Best for: Teams using AI assistants for pull-request review on medium to large repositories who want a permissively licensed, local code graph.
Price: Free and open source (MIT). Optional cloud embedding providers (Gemini, Voyage, OpenAI-compatible) bill you separately.

A mature scanner wired neatly into coding agents, whose sensible default of scanning every AI edit spends a Free plan's monthly tests in days.
Best for: Teams already paying for Snyk who want coding agents to check and fix the security of the code they write.
Price: Free with the Snyk CLI; scans count against your Snyk plan. Free: 100 Snyk Code tests a month, 5 projects. Team from $25 a month (up to 10 developers, 1,000 Code tests). Enterprise uses credits.

Exceptional code intelligence for agents, held back by a noncommercial licence that most employers cannot accept without a paid deal.
Best for: Individual developers, researchers and open-source maintainers on noncommercial projects who want the deepest structural view of a codebase for their agent.
Price: Free for noncommercial use (PolyForm Noncommercial 1.0.0). Commercial use, managed SaaS and self-hosted enterprise deployments need a licence from Akon Labs; prices are not published.

A tidy, well-patched way to give a shell-less chat client Git, though any agent with a terminal already has a better one.
Best for: People using chat-style MCP clients who want the model to inspect and commit local changes without shell access.
Price: Free and open source.

Gives a coding agent the one thing it lacks in game development: the ability to run the game and read what broke.
Best for: Godot developers who use a coding agent and want it to test changes by running the game.
Price: Free and open source under MIT; Godot is free.

Jev's guardrail tools with nothing to install, at roughly two and a half times TypeSafe's own price and with a second company reading every prompt.
Best for: People who want to try Jev from Claude, Cursor or another remote-capable client without managing keys or installing anything.
Price: 100 Vio Credits per million input tokens at the launch rate; output is not billed. Free plan: 2,500 one-time credits. Top-ups from $10 for 10,000 credits, which works out at about $0.10 per million Jev input tokens.

A free, keyless page reader that does exactly one job, and hands whatever a stranger's web page says straight to your model.
Best for: Developers who want a basic, free page reader for an MCP client that lacks one.
Price: Free and open source.

A sensible way for a small team to share one TypeSafe key across claude.ai and ChatGPT, and an odd amount of gateway for one developer.
Best for: Teams that already use AnythingMCP, or want an audited, shared Jev endpoint for claude.ai and ChatGPT users.
Price: Self-hosted Community Edition is free; AnythingMCP Cloud has a 7-day trial, then €19 a month for one user or €49 for up to three. Jev is billed separately by TypeSafe at $0.042 per million input tokens.

A readable local file and a substring search make this a decent notebook for one agent, and a weak long-term memory once the graph grows.
Best for: Hobbyists and developers learning how persistent memory over MCP works.
Price: Free and open source.

Redundant on today's reasoning models, it now justifies its 921-token overhead only as a visible planning trace or as scaffolding for small models.
Best for: People using smaller or older models who want a visible step-by-step planning trace.
Price: Free and open source.
