Dev intelligence layer: 7 MCP tools for graph-powered codebase reasoning.
Overview
Graqle builds a local knowledge graph from code, docs and policies and gives AI agents graph-powered codebase reasoning plus a decision gate.
- What you can do
- Scan repositories, documents, policies and ADRs into one connected knowledge graph
- Record knowledge and ask questions, getting answers with confidence and cited sources
- Evaluate a proposed agent action through a decision gate that returns EXECUTE, REPLAN, HOLD, REJECT or ESCALATE with reasons
- Write signed, hash-chained provenance records of each decision for later audit
- Share one graph across several agent sessions through a local server and thin relays
- When to use it
- Useful when an assistant needs durable, organisation-wide context about a codebase and its policies rather than a single chat session, or when agent actions should be checked against policy and evidence before they run.
- Requirements
- Installed locally as the PyPI package graqle (Python); optional extra for PDF, DOCX, PPTX and XLSX. The decision gate is off by default and needs GRAQLE_DAG_ENABLED plus many GRAQLE_DAG_* settings, a signing key and a coverage policy. The shared server needs authentication unless local development mode is enabled.
Installation
In SourceWeft
- Open Graqle in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.

What GraQle does
- Remembers. Turns your code, documents, policies and decisions into one connected knowledge graph that lasts beyond a chat session.
- Checks. Before an agent acts, the Decision Assurance Gate checks the action and answers EXECUTE, REPLAN, HOLD, REJECT or ESCALATE - with the reason and a signed record.
- Shares. One graph serves a whole team of agents - Claude Code, Cursor, Codex, Copilot - each with its own permissions and its own files.
Works with any model: Anthropic, OpenAI, AWS Bedrock, Ollama, Gemini and more - or fully offline.
Quickstart
Connect it to your AI tool (Claude Code, Cursor, Windsurf, VS Code):
PDF, DOCX, PPTX and XLSX: pip install "graqle[docs]".
Check every decision
Most AI tools give you one confidence number. GraQle asks separate questions before an agent acts - and a good answer to one never hides a failed answer to another:
- Allowed? Policy valid, actor authorised, evidence current, arguments exactly the approved ones. Any "no" stops the action.
- Consistent? Contradicting facts are tracked in the graph, and a change updates every decision that depends on it.
- Sure enough? Confidence is measured per dimension, not blended into one score.
- On track? Unreliable step sequences are sent back to replan within a retry budget.
- Who approves? Authority is checked for the action's impact level.
Every decision leaves a sealed record: a signed, hash-chained provenance event, exportable to W3C PROV-O and checkable with SHACL, so an auditor can verify it with standard tools. The gate is off by default: installing or upgrading GraQle changes nothing until you switch it on.
Turn it on, per project:
- Set
GRAQLE_DAG_ENABLED=truein the environment where GraQle runs (or in your.env). - Provide the required settings. GraQle ships no thresholds, salts or keys: you choose them. Start from the
GRAQLE_DAG_*section of.env.exampleand fill in every placeholder (salt, thresholds, signing key id and version, calibrator version, and the others listed there). Put the values in the environment, or in a private file atGRAQLE_DAG_SECRETS_PATH(default.graqle/graqle_secrets.yaml); the environment wins. - Start as usual. If a required value is missing, GraQle raises a configuration error that names it the first time the gate settings load. There is no silent fallback.
Check it: python -c "from graqle.assurance.settings import is_dag_enabled; print(is_dag_enabled())" prints True.
To switch it off again, unset the flag or set it to false. Details: operating the gate.
One memory for a team of agents
Several agents on one codebase usually means several copies of the same graph in memory. GraQle can hold it once:
- Less memory. Each session runs a small relay instead of a full copy (measured on a 20,000-node graph: 3 separate servers 687 MB, shared server + 3 relays 493 MB).
- Learning is shared at once across all sessions.
- Each session keeps its own gates and its own files - file work happens on each user's own machine.
- Teammates connect over an SSH tunnel, or HTTPS with a token.
- Several projects, separate graphs on one server (Team and Enterprise).
Turn on the decision gate (opt-in, baseline tier)
The decision gate is off unless GRAQLE_DAG_ENABLED is set; with it off nothing changes. Turn it on:
- Create an ed25519 signing key (PEM, mode
0600) and a key manifest that lists its public key (graqle.assurance.key_manifest_store.save_manifest), plus a coverage policy file. - Set
GRAQLE_DAG_ENABLED=1and the requiredGRAQLE_DAG_*settings:SIGNING_KEY_ID,SIGNING_KEY_VERSION,SIGNING_KEY_PATH,COVERAGE_POLICY_PATH,CONFIG_SALT,CAP_VALUE,HG05_POISONING_THRESHOLD,HG07_MATERIALITY_THRESHOLD,CALIBRATOR_VERSION,TRAJECTORY_ESTIMATOR,MAX_RETRY_BUDGET,CIRCUIT_BREAKER_WINDOW,SCOPE_KEY_FIELDS_REF,MERGE_PRIORITY_REF. There are no built-in values for these; you choose them. - Register the actors that may take MEDIUM-risk calls (for example
GRAQLE_RBAC_ACTORS_JSON). An actor with no registered role is closed by hard gate HG-06. - Start your process. The packaged default runtime provider is registered at start-up. If it
cannot be built the process fails at start-up with an error naming
register_runtime; supply your own provider withgraqle.assurance.adapter.register_runtime(provider)if you need one.
Baseline-tier decisions are governed by rule DAG-RT-BASELINE-ADMIT. No projection score,
reliability or residual risk is computed or recorded for them. EXECUTE only when risk is LOW,
impact is zero and all hard gates pass; anything else is HOLD (DAG-RT-NO-EVIDENCE) or, when a
hard gate fails, REJECT. MEDIUM and above routing requires explicit configuration. Every decision
is written as a signed, hash-chained provenance event; if it cannot be written the call is not
executed.
This is a policy-scoped authorisation at evidence tier BASELINE. It is not informed by the graph
and is not a safety verification. Evidence-fed scoring arrives in 0.88 (CR-DAG-088-1).
python scripts/dag_wheel_e2e.py runs these steps against the built wheel in a clean virtualenv.
Trust
- Local-first, no telemetry. The graph is a file you control; nothing phones home.
- Secure by default. The server needs authentication unless you explicitly switch on local development mode; graph uploads can never silently overwrite each other.
- Signed releases. Sigstore-signed wheels, CycloneDX SBOM, reproducible builds.
- Regulated work. Audit trail and evidence exports for your own EU AI Act file - GraQle provides evidence, it does not claim to make you compliant. Details
