api record

Read-only tools over the open data of the GreenCycle Compound Atlas (https://greencyclepedia.com). Use them for any question about cannabis compounds (cannabinoids such as THC, CBD, CBG and CBN, terpenes such as myrcene, limonene and beta-caryophyllene, flavonoids), the receptors, channels and enzymes they act on (CB1, CB2, TRPV1, GPR55, 5-HT1A, PPAR-gamma, FAAH, CYP3A4 and more) with measured binding values, where in the human body those targets sit, the evidence grade for medical conditions, the PubMed studies behind each finding, registered clinical trials and the cultivars a laboratory…

_ is it live, free and safe measured by this hub
Is greencyclepedia live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is greencyclepedia free to use?
Yes — the hub reached it with no key and no payment.
What tools does greencyclepedia have?
13 tools: search, fetch, search_compounds, get_compound, compare_compounds, get_target, list_structures_for_target, search_conditions, ….
Is greencyclepedia safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

    The full text of one atlas record by the id that search returned ("compound:cbd", "target:CB1", "condition:epilepsy", "trial:NCT03883360", "cultivar:STRAIN0001"): what it is, the targets and effects with evidence grades, measured binding values, cautions, every source (PubMed ids with links) and the citation line, with the atlas url.

  • search_compounds unknown never probed

    Use for lists of cannabis compounds: find the compounds mapped onto the human body (curated atlas records and database compounds with a measured, sourced value at a target placed in tissue) by name, chemical class, record type or molecular target (for example every compound acting at CB2, TRPV1, 5-HT1A or FAAH, or every terpene). Returns identity, PubChem CID, record type, targets and the atlas url. Use get_compound for one full record. Educational reference, not medical advice.

  • get_compound unknown never probed

    Use for "what does THC, CBD or myrcene do in the body": the full record of one mapped compound by atlas id, Cannabis Compound Database id, name or PubChem CID. A curated record gives identity and structure identifiers, every target with the action, effect, evidence grade, body structures and PubMed identifiers, the measured binding values (pKi, pIC50, pEC50) from the IUPHAR/BPS Guide to PHARMACOLOGY, the cultivars a laboratory measured it in with their sources, an evidence summary, its cautions and a ready citation. A database compound gives its identity and every measured value at a placed target with its PubMed id or DOI. Educational reference, not medical advice. No doses.

  • compare_compounds unknown never probed

    Use for "THC versus CBD" and similar questions: two to four compounds side by side, target by target, with each action, evidence grade, measured binding values and PubMed identifiers, the targets they share and the atlas comparison page when one exists.

Trials are kept as administered in each trial; doses are left out on purpose. Educational reference, not medical advice. Not a diagnostic or dosing tool.

    Use for strain chemistry: one cultivar from the laboratory measurements the atlas uses (Cannabis Compound Database values, mg per gram of dry flower), by CCD id or name: every atlas compound measured in it with the mean, the number of values and the PubMed identifier of each source. Cultivar names are a poor guide to chemistry (PMID 35588111, PMID 39137353); never the community strain index. Educational reference, not medical advice.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 5376584b637978fa.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/5376584b637978fa/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/5376584b637978fa/badge.svg)](https://brick.blue/agent/5376584b637978fa?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
