Chartbrew MCP

TypeScript MCP server built on the official MCP SDK for documented Chartbrew API endpoints.

Chartbrew MCP in action — managing analytics resources through natural language.

- Teams: list, get
- Connections: list, get, test, create, update, delete
- Datasets: list, get, fetch data, create, update, delete
- Data Requests: list, run
- Dashboards (projects): list, get, create, update, delete
- Charts: get, create, query, delete

- Variable binding create/update endpoints

Chartbrew API docs specify Bearer token authentication.

- Authorization: Bearer <CHARTBREW_API_KEY>

- unrestricted: all implemented tools are available.
- restricted: only data-retrieval/query tools are available (list/get/fetch/query/run/test). Create/update/delete tools are disabled.

You can provide these values in either of two ways (pick one):

- .envfile in thismcpfolder— copy.env-templateto.envand fill in the values. The server auto-loads it on startup.
- Theenvblock of your coding agent's MCP config— set the variables directly in theenvobject of the server entry (e.g..mcp.jsonfor Claude Code, or the equivalent MCP config for Codex, GitHub Copilot, OpenCode, Kimi Code, etc.). Use this when you don't want a local.envfile.

The server uses stdio transport and is intended to be launched by an MCP client host.

Releases include both raw binaries and compressed archives (.zipfor Windows,.tar.gzfor Linux/macOS) — grab the archive for a smaller download, then extract it.

- Windows:downloadchartbrew-mcp-windows-x64.zip(orarm64), extract, run the.exe.
- macOS / Linux:download e.g.chartbrew-mcp-darwin-arm64.tar.gz, extract, then make it executable once:chmod +x chartbrew-mcp-darwin-arm64
- macOS Gatekeeper:if macOS blocks the unsigned binary, remove the quarantine attribute:xattr -d com.apple.quarantine chartbrew-mcp-darwin-arm64

You donotneed a.envfile — set configuration through your MCP client'senvblock (or the OS environment). Example for Claude Desktop / Claude Code (.mcp.jsonorclaude_desktop_config.json):

{ "mcpServers": { "chartbrew": { "command": "/absolute/path/to/chartbrew-mcp-darwin-arm64", "env": { "CHARTBREW_API_KEY": "your-api-key", "CHARTBREW_API_BASE_URL": "https://api.chartbrew.com", "CHARTBREW_TOOL_MODE": "restricted" } } } }

npm install npm run build:bin # writes binaries to dist-bin/

Afternpm installandnpm run build, register the server with your MCP host. The server runs over stdio vianode dist/index.js. Replace<ABSOLUTE_PATH_TO_MCP_DIR>with the absolute path to thismcpdirectory and set your API key.

If you use Claude Code, you can register the server directly from the terminal instead of editing a config file:

claude mcp add chartbrew \ -e CHARTBREW_API_KEY=your-api-key \ -e CHARTBREW_API_BASE_URL=https://api.chartbrew.com \ -e CHARTBREW_TOOL_MODE=restricted \ -- node <ABSOLUTE_PATH_TO_MCP_DIR>/dist/index.js

- Usehttp://localhost:4019forCHARTBREW_API_BASE_URLon a self-hosted instance (change the port if yours differs).
- Add-s user(or-s project) to control the scope the server is registered in.
- Verify withclaude mcp list; remove withclaude mcp remove chartbrew.

Known documentation limitations reflected in implementation

- ID types are inconsistent in docs (number vs string), so tool inputs accept strings.
- Some create/update payload required fields are not consistently documented, so payload is typed as flexible object.
- Dataset fetch filters query-object encoding is undocumented; this server sends object values as JSON strings.
- Error response schemas vary by endpoint; parser handles both error and message fields when available.

Zero-dependency persistent AI memory using SQLite. Dual-store, pluggable embeddings, 10 MCP tools.

Codebase memory for coding agents, with no embeddings and no API key. A deterministic AST index answers "which files are relevant to this task?" in milliseconds, and agents write durable notes about the repo that are content-hash checked — a note flags itself stale the moment the code it describes changes. Notes are markdown inside the repo, so they commit and review alongside your code.

Perform semantic search and retrieval augmented generation over your Apple Notes.
