api record

Peptide Library (https://peptidelibrary.app) is an educational peptide research library. Use these tools to look up peptide research profiles, compare them, search the educational content and do unit arithmetic. Every result is for research and education only and is not medical advice. The server never gives dosing, administration or purchasing guidance: do not infer doses, regimens or injection instructions from its data. Cite the Peptide Library URL returned with each result, keep human, animal and lab evidence separate, and say plainly when a field is "not_documented" instead of filling…

_ is it live, free and safe measured by this hub
Is peptide-library live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is peptide-library free to use?
Yes — the hub reached it with no key and no payment.
What tools does peptide-library have?
10 tools: get_peptide_details, compare_peptides, search_research, convert_units, solution_concentration, blend_concentrations, cost_per_amount, get_peptide_categories, ….
Is peptide-library 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.

  • get_peptide_categories open 2h ago

    List the Peptide Library research categories (e.g. GLP-1/Metabolic, Cognitive, Longevity) with a description, the number of profiles and every profile in each, with links. Use a category id with search_peptides to filter.

  • get_research_trends open 2h ago

    This week's most-researched peptides in the Peptide Library community (Trending Now, last 7 days): rank, share of researchers and growth as percentages, with what moved. Aggregate and privacy-preserving: no head counts, no individual activity, small cohorts suppressed. Popularity is not evidence of safety or effectiveness.

  • search_peptides open 2h ago

    Search the Peptide Library research database by name, synonym or alias (fuzzy), optionally filtered by research category or research area. Returns short educational profiles with evidence level and the canonical Peptide Library URL. Use get_peptide_details for the full profile. No dosing information.

  • get_peptide_details unknown never probed

    Full educational research profile for one peptide: classification, mechanism and targets, research areas, evidence by tier (regulatory label, controlled human trials, other human studies, secondary reports, animal and in-vitro research) with cited sources, safety and side effects, regulatory status (FDA, WADA), review dates and the canonical Peptide Library URL. Fields the profile lacks are "not_documented". Dose figures and administration instructions are never included.

  • compare_peptides unknown never probed

    Side-by-side research comparison of 2-3 peptides on structured profile fields: mechanism and targets, research areas, evidence level and human-trial availability, safety and side effects, FDA/WADA status, half-life and studied routes, with references. Each row says whether the values are the same, different, partial, not comparable or incomplete; missing data is never filled in and the comparison never ranks peptides. Suitable for tables. No dosing information.

  • convert_units unknown never probed

    Convert an amount between mg and mcg exactly. IU ↔ mass conversion only works with a peptide whose profile documents an IU-per-mg factor (pass `peptide`); otherwise the result is an iu_factor_missing issue, never an assumed factor. Pure arithmetic: not a dosing recommendation.

_ 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 e0306964c294f681.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e0306964c294f681/claim. Over MCP: the claim_endpoint tool.

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.
