Was ist Codna MCP?

Codna ist ein MCP server. Ermöglicht es AI Agents, Issues zu triagieren, Bugs zu fixen, die Erreichbarkeit von SARIF-Scanner-Ergebnissen zu verifizieren und semantischen Code-Recall innerhalb eines Repositories durchzuführen.

Zusammenfassung generiert aus dem README des Projekts

Über Codna MCP server

Codna bietet Repository-Intelligence für AI Agents, indem es Codebases mappt, um Bugfixing und Issue-Triage zu erleichtern. Es fungiert als MCP server über stdio und ermöglicht die Integration in Clients wie Cursor oder Claude Desktop. Entwickler können es lokal oder in der Cloud ausführen, wobei dieselbe Engine wie im CLI verwendet wird. Das System erfordert einen einmaligen kostenlosen Community-Login via codna login, um die Tool-Ausführung zu aktivieren, während spezifische Aufgaben wie das Fixen von Bugs einen Model-Provider-Key von Diensten wie Anthropic, OpenAI oder Gemini benötigen.

Der Server bietet fünf primäre Tools: codna_triage zum Finden von relevantem Code, codna_secure zur Verifizierung der Erreichbarkeit von SARIF-Scanner-Findings von Tools wie CodeQL oder Snyk, und codna_recall für semantische und lexikalische Code-Suche. Für die aktive Entwicklung kann codna_fix Ursachen identifizieren und sogar Pull Requests eröffnen, sofern ein GitHub Token bereitgestellt wird. Ein einzigartiges Feature ist die On-Device Memory Runtime, die es ermöglicht, dass Code-Recall nach dem initialen Setup ohne Netzwerkaufrufe vollständig offline funktioniert.

Codna

Understand. Fix. Evolve.

Agents read your code. Codna understands it.

Codna maps a repository before it spends a token. It then reviews pull requests, fixes bugs and proves which scanner findings are reachable. The same codna command runs on your machine, in the GitHub Action and behind the GitHub App.

Runs on your machine or your cloud. Your code never leaves without your key.

Install

pip install codna          # or: pipx install codna · uv tool install codna
codna --version

Python 3.12–3.13. Wheels for macOS on Apple silicon and Linux x86_64. git on your PATH. Nothing else to install: no Node, Bun, Docker or server. The agent runtime ships inside the wheel.

Local commands need no Codna key. fix and review use your own model provider key, stored in the OS keychain and never printed:

codna key set anthropic    # also: openai, gemini, google, groq, mistral, openrouter, xai, cursor

Commands

codna triage . --issue "checkout total is wrong"     # suspect files. Deterministic. 0 LLM tokens.
codna review . --pr 123 --post                        # findings with a verdict on the pull request
codna fix . --tests --apply --max-iterations 3        # patch, re-run your tests, re-fix until green
codna fix <git url> --ref <sha> --issue "…" --open-pr # push a branch and open a pull request
codna secure . --from-sarif results.sarif             # which scanner findings are reachable. 0 LLM tokens.

codna fix prints the root cause, the impacted symbols, the blast radius, its confidence and a regression risk. --open-pr needs a git URL and a GitHub write token. codna review posts one inline comment per finding with severity, category and a suggestion block, and an Approve when the diff is clean at medium and high. codna secure reads SARIF 2.1.0 from CodeQL, Semgrep, Snyk, Trivy or any other scanner.

Other commands: init, status, doctor, login, key, impact, memory export, report. Full reference: docs.codna.ai/reference/cli.

MCP server

Run Codna as a Model Context Protocol server over stdio — the same engine the CLI uses, inside Cursor, Claude Desktop, or your own agent:

pipx install "codna[mcp]"       # or: pip install "codna[mcp]"
codna mcp                       # serve over stdio
codna mcp install --client cursor     # optional: write the client config for you (or --client claude)

Five tools, each returning JSON; a failure comes back as codna_<tool> error: … text and never crashes the server:

Tool	What it does	Needs
`codna_triage`	Understand a repo and locate the code relevant to an issue. Deterministic, 0 LLM tokens.	free `codna login`
`codna_secure`	Prove which SARIF scanner findings (CodeQL, Semgrep, Snyk, Trivy) are reachable. Read-only, 0 LLM tokens.	free `codna login`
`codna_recall`	Recall code from local on-device memory — semantic + lexical search, fully offline.	free `codna login` (which also installs the on-device runtime)
`codna_fix`	Root-cause and plan a fix (read-only by default); with `open_pr=true` pushes a branch and opens a real PR.	free `codna login` + provider key (BYOK; + `GITHUB_TOKEN` for `open_pr=true`)
`codna_report_bug`	File a bug, feature, or question to thyn-ai/feedback.	free `codna login` + `GITHUB_TOKEN` (else returns a pre-filled URL)

Introspection (initialize/tools/list) needs no credentials. Executing any of the five tools requires the one-time free community login (codna login — device authorization, free community license) — fully offline thereafter. codna_fix additionally needs a provider key (BYOK, e.g. ANTHROPIC_API_KEY); codna_report_bug needs GITHUB_TOKEN or it returns a pre-filled issue URL; codna_recall additionally uses the on-device memory runtime that the same codna login installs. Full reference: docs.codna.ai/guides/mcp.

Code memory

Code memory and recall run on your machine after a one-time free codna login (device authorization), which also installs the signed on-device runtime. From then on, recall runs fully offline: no key, no network calls. The optional codna[memory] extra adds the on-device semantic reranker; without it, recall ranks lexically.

What leaves your machine

Repository mapping, triage, recall and impact run offline. No model is involved.
fix and review send one issue-specific evidence bundle to the provider you chose, under your key. Not the repository.
Secret redaction is always on and cannot be turned off.
privacy.egress: fail-closed in codna.yaml refuses to run tests without network denial and skips registry lookups during review.
Source distributions exclude runtime binaries, keys, .env files and logs.

Codna MCP Fragen

Wie füge ich Codna MCP zu Claude Code hinzu?

Führe claude mcp add --env ANTHROPIC_API_KEY=<YOUR_ANTHROPIC_API_KEY> --env CODNA_API_KEY=<YOUR_CODNA_API_KEY> --env GEMINI_API_KEY=<YOUR_GEMINI_API_KEY> --env GITHUB_TOKEN=<YOUR_GITHUB_TOKEN> --env OPENAI_API_KEY=<YOUR_OPENAI_API_KEY> codna-cli -- uvx codna in deinem Terminal aus. Füge --scope user hinzu, damit der Server in jedem Projekt verfügbar ist.

Wie füge ich Codna MCP zu Cursor hinzu?

Öffne ~/.cursor/mcp.json und füge den Server unter mcpServers hinzu, mit der Cursor-Config aus dem Installationsabschnitt oben.

Sendet Codna mein gesamtes Repository an ein LLM?

Nein, fix und review senden nur ein auf das spezifische Issue zugeschnittenes Evidence-Bundle unter deinem Key an deinen gewählten Provider, nicht das gesamte Repository.

Wie nutze ich Codna mit Cursor oder Claude Desktop?

Du kannst den MCP server via pipx installieren und den install command nutzen, um die Client-Config für Cursor oder Claude automatisch zu schreiben.

Kann ich Codna offline nutzen?

Ja, Repository-Mapping, Triage, Recall und Impact-Tools laufen offline, und Recall läuft nach einem einmaligen Login vollständig offline.

Welche Scanner-Ergebnisse kann Codna analysieren?

Codna kann die Erreichbarkeit von Findings von CodeQL, Semgrep, Snyk, Trivy oder jedem anderen Scanner nachweisen, der SARIF 2.1.0 bereitstellt.
