Local-first AST-based code context engine exposed over MCP.
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":"locker-room-tools-synapse-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

Use Python >=3.12. 2. Install Synapse as a managed CLI tool: `uv tool install locker-room-tools-synapse-mcp`. 3. Connect it globally to your agent: `synapse install codex` 4. Restart the agent once. Replace `codex` with `amp`, `antigravity`, `claude-code`, `cline`, `continue`, `copilot`, `copilot-vscode`, `crush`, `cursor`, `droid`, `gemini`, `goose`, `hermes`, `kimi`, `kiro`, `opencode`, `openclaw`, `qwen`, `roo`, `windsurf`, or `zed`. No repository files are created. The first `synapse_orient` or `synapse_inspect` call initializes the local index and daemon automatically. See [Installation and lifecycle](docs/installation.md) for upgrades, custom scopes, troubleshooting, and uninstall instructions. See [MCP tools](docs/tools.md) for tool contracts and recommended agent flows. ## Development Create a virtual environment and install the repository with development dependencies: `uv venv && uv pip install -e ".[dev]"`. Then run `synapse grammars install` once. Grammar installation is an ex…
