agentmako

agentmako is a local-first codebase intelligence engine for AI coding tools.

It gives agents like Codex, Claude Code, Cursor, and local harnesses a typed MCP toolset for understanding a project before they edit it. Mako indexes your repo, builds local SQLite-backed facts, tracks diagnostics and review notes, and returns structured context packets instead of making the agent rediscover everything with raw grep.

Mako is built for the first mile of coding-agent work:

What files matter? What routes, symbols, tables, diagnostics, and prior findings are relevant? What should the agent read next?

What You Get

• MCP server for coding agents: agentmako mcp

• Local dashboard: agentmako dashboard

• Queryable workflow orientation: mako_help

• Deterministic context packets: context_packet, reef_scout

• _hints on tool results so agents get result-specific next steps

• Central MCP annotations so clients can distinguish safe reads, live reads, and local-state mutations

• Code search and structure tools: cross_search, live_text_search, ast_find_pattern, repo_map

• Reef Engine facts and findings across indexed, working-tree, and staged state

• Reef convention extraction for auth guards, runtime boundaries, generated paths, route patterns, and schema usage

• TypeScript, ESLint, Oxlint, Biome, and staged git diagnostic ingestion

• Hot-reloaded .mako/rules YAML rule packs, including primitive cross-file helper-bypass rules via canonicalHelper

• Optional Postgres/Supabase schema snapshots and read-only DB inspection

• Local DB review comments for notes on tables, RLS, triggers, publications, subscriptions, and replication

• Recall, acknowledgements, and agent feedback for repeated review work

Everything important runs locally. No hosted service is required.

Install

Requires Node.js 20 or newer.

npm install -g agentmako

Confirm the CLI is available:

agentmako --version
agentmako doctor

You should see green checks for configuration and the local API service.

Prefer to build from source (e.g. to contribute)? See Develop From Source at the bottom of this file.

Happy Path Setup

1. Attach your real project

Go to the project you want Mako to understand:

cd C:/path/to/your/project

Attach and index it:

agentmako connect . --no-db

Use --no-db for the first run. It gets the code intelligence path working before adding database scope.

2. Confirm Mako sees the project

agentmako status .
agentmako tool list

Run a real scout query:

agentmako --json tool call . reef_scout "{\"query\":\"where should I inspect auth route state?\"}"

If that returns ranked candidates, facts, or findings, the core setup is working.

reef_scout classifies broad requests before ranking. App-flow questions favor file, route, and finding evidence; RLS/schema questions favor database facts and review comments. To inspect project rules of thumb directly:

agentmako --json tool call . project_conventions "{}"

3. Configure your MCP client

Add this to your MCP client config:

{
  "mcpServers": {
    "mako-ai": {
      "command": "agentmako",
      "args": ["mcp"]
    }
  }
}

Restart the MCP client and confirm the mako-ai server starts.

In the agent, start with one of these tools:

• tool_search when you need to find the right Mako tool

• context_packet when you have a coding task and want starting context

• reef_scout when you want intent-ranked project facts/findings/history

• file_preflight before editing one risky file and you need findings, diagnostic freshness, conventions, recent runs, and ack history together

• reef_diff_impact mid-edit or before review when you need changed-file callers, caller findings, and convention risks in one packet

• extract_rule_template after a fix lands and you want a reviewable .mako/rules YAML draft for the same bug shape next time

• project_conventions when you need discovered auth, runtime, route, generated-file, or schema-usage conventions

• ask when you have a natural-language repo question

4. Optional: use an agent plugin

Plain MCP works anywhere, but the bundled plugins add Mako-specific skills and include the same agentmako mcp wiring.

Prerequisites:

• Claude Code installed

• Node.js 20+ on PATH (the plugin runs npx -y agentmako mcp, which fetches the published agentmako package automatically — no separate global install required)

• Your target project already attached with agentmako connect

Claude Code stable path:

claude plugin validate .\mako-ai-claude-plugin
claude --plugin-dir .\mako-ai-claude-plugin

New generated plugin layouts:

claude plugin validate ./plugins/claude-code
codex marketplace add ./plugins
ln -s "$(pwd)/plugins/cursor" ~/.cursor/plugins/local/mako-ai
gemini extensions install ./plugins/gemini

Inside the agent, confirm the mako-ai MCP server is connected.

The plugin exposes these skills:

• /mako-ai:mako-guide

• /mako-ai:mako-discovery

• /mako-ai:mako-trace

• /mako-ai:mako-neighborhoods

• /mako-ai:mako-graph

• /mako-ai:mako-database

• /mako-ai:mako-code-intel

• /mako-ai:mako-workflow

Use the plugin when you want Claude Code to load Mako-specific guidance for which tools to call and how to interpret their results.

5. Optional: launch the dashboard

From your target project:

agentmako dashboard .

This starts the local API, harness service, and web dashboard.

6. Optional: add Supabase/Postgres awareness

Mako works without a database. Add this only after code intelligence is working.

For a one-time interactive setup:

agentmako connect .

For CI or scripted setup using an environment variable:

set DATABASE_URL=postgres://...
agentmako connect . --db-env DATABASE_URL --yes

Then refresh and verify the local schema snapshot:

agentmako refresh .
agentmako verify .

Interactive mode stores database secrets in your OS keychain by default. Project config stores references, not plaintext DB URLs.

Normal Daily Loop

From the target project:

agentmako status .
agentmako dashboard .
agentmako --json tool call . context_packet "{\"query\":\"fix the broken auth callback route\"}"

For staged review checks:

agentmako git precommit . --json

For database review notes:

agentmako --json tool call . db_review_comment "{\"objectType\":\"replication\",\"objectName\":\"supabase_database_replication\",\"category\":\"review\",\"comment\":\"Check publication coverage before relying on realtime events.\",\"tags\":[\"supabase\",\"replication\"]}"

Develop From Source

If you want to hack on Mako itself, clone and build instead of installing from npm.

Prerequisites:

• Node.js 20 or newer

• Git

• Corepack (corepack enable, included with modern Node.js)

git clone https://github.com/drhalto/agentmako.git
cd agentmako
corepack pnpm install
corepack pnpm run build
npm link ./apps/cli

npm link ./apps/cli makes the source-built CLI available as agentmako on your PATH, replacing any global npm install. Re-run corepack pnpm run build after pulling changes.

To go back to the published version: npm install -g agentmako.

Development Checks

corepack pnpm run typecheck
corepack pnpm run build
corepack pnpm run test:smoke:reef-tooling
corepack pnpm run test:smoke:reef-model-facing-views

Full verification:

corepack pnpm test
