Verdigraph tools (4)
write = sends, deletes, buys or postsbuild_brainFreeCompile an agent file into a deterministic, content-addressed brain. content = the file as a string; format = verdigraph_genome | claude_project_export | openai_assistant | prompt_list | auto. Returns brain_id, content_hash, node/edge counts, the 9-invariant firing report, and provenance. Identical bytes always produce the identical brain_id (VB1). include_document=true returns the full graph.
describe_agentFreeReturn capabilities and input contract.
detect_formatFreeDetect which supported agent-file format the content is (verdigraph_genome, claude_project_export, openai_assistant, prompt_list) before building.
verify_brainFreeMachine-check a cognition claim: recompute the brain from the submitted content and compare against the claimed brain_id and/or content_hash. valid=true iff every claimed identifier matches the deterministic recomputation (VB3).

What the publisher says
From the Verdigraph repository's README, as published. We do not edit it. Read it on GitHub
Viridis Agent Fleet: open-source agents for the agent economy
Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.
Licensed Apache-2.0. Run any agent yourself, fork it, embed it.
Run an agent locally (free, forever)
pip install -r requirements-dev.txt
python3 agent-escrow-agent/adapters/mcp_server.py # stdio MCP
python3 run_fleet_tests.py # every agent's invariant testsOr use the hosted fleet
https://mcp.viridisconservation.com runs all agents as one managed MCP service:
Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.
Boundary
This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.

- Yes, by our scan: it is graded A (91/100). Read the Verdigraph safety report
- How do I install Verdigraph?
- It runs remotely at mcp.viridisconservation.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
- Does Verdigraph need an API key?
- Not as far as the registry entry and our scan can tell: no credentials are declared or required.
- Is Verdigraph maintained?
- The last commit was 40 days ago (2026-09-25). The latest release is v0.1.0.
- Is Verdigraph up?
- 100% of our last 28 checks got an answer. We check remote servers about four times a day.
- What can I use instead of Verdigraph?
- Servers from other publishers that do the same job: Basic Memory MCP server, OpenWorkProof MCP server and Openflowkit MCP server.
- How does Verdigraph compare with other AI and agents MCP servers?
- safety score 91/100 (higher than 88% of 4,460 AI and agents servers); tools 4 (the typical AI and agents server has 6); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
