Local, read-only MCP tools for CAN databases and capture logs
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"canforge-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# canforge-mcp [](https://pypi.org/project/canforge-mcp/) [](https://github.com/canforge/canforge-mcp/actions/workflows/ci.yml) [](https://pypi.org/project/canforge-mcp/) [](LICENSE) `canforge-mcp` is a local, read-only MCP server for inspecting DBC files and decoding CAN capture logs. Files stay on the machine running the server. The server exposes bounded tools instead of uploading captures or returning unbounded traces. ## Tools | Tool | Purpose | |---|---| | `dbc_info` | DBC version, message/signal/node counts, and node names | | `list_messages` | Bounded message summaries, with optional search | | `get_message` | Full message and signal detail by name or arbitration ID | | `search_signals` | Bounded signal search across a DBC | | `decode_frame` | Decode one hexadecimal CAN payload | | `validate_dbc` | Structured DBC validation issues | | `diff_dbcs` | Added, removed, and changed messages and signals | | `probe_log` | Detect a log format and read header metadata | | `log_stats` | Frame count, span, ID counts, and median cycle times | | `log_signal_inventory` | One-pass inventory of DBC signals observed in a log | | `read_frames` | Bounded raw-frame samples with ID and time filters | | `decode_log` | Bounded decoded frames from a DBC and log | | `signal_timeseries` | Downsampled timestamp/value points for one signal | See [the tool reference](docs/tools.md) for arguments, return shapes, and hard caps. ## Install Run directly with `uvx`: ```bash uvx canforge-mcp ``` Or install with pip: ```bash pip install canforge-mcp canforge-mcp ``` Requires Python `>=3.11`. ## Configure Claude Code: ```bash claude mcp add canforge -- uvx canforge-mcp ``` Claude Desktop (`claude_desktop_config.json`): …
