Studies and clinical trials for BPC-157, retatrutide, tirzepatide and 160+ peptides, with sources.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • resolve_peptide

    Return peptide IDs and name matches for a name, alias or code. Use this before other calls when the name is unclear. Use search_peptides instead to browse or filter many peptides. Matching order: exact alias, normalized alias, trigram similarity, then edit distance. Normalization

  • get_peptide_brief

    For a dose question, use studied_doses together with get_community_practice. Return a precomputed summary of one peptide: identity, sequence, checked findings by evidence class, trials, key findings with citations, coverage and notices. regulatory gives approval by place and use,

  • get_community_practice

    Return what community sources report about how people use one peptide: uses, regimens (route, amount, how often, how long), reported side effects, cautions and regulatory status notes such as US compounding policy, each line with its sources. Community-reported, not tested in tri

  • search_peptides

    Return peptides with identity and evidence counts. Use this to browse or filter by text, category, kind, evidence level, registry level or the curated launch list. Use resolve_peptide instead for one unclear name, or get_peptide_brief for one peptide summary. evidence_level comes

  • search_findings

    Return checked findings with exact total_count and source sentences in included.passages. Each finding is one claim from one paper. Use this for specific outcomes, with filters for peptide, evidence class, design, claim type, peptide role, direction, outcome group, body system an

  • search_publications

    Return stored papers with citation identifiers and extraction status. Use this for paper discovery, publication dates or unchecked coverage. Use search_findings instead for checked claims and source sentences, or get_peptide_brief for a peptide overview. extraction_status identif

  • search_trials

    Return registered clinical trials with registry status, phase, posted-results status and peptide role. Use this for clinical development and trial records. Use search_findings instead for checked study results, or get_record for one full trial. The default role=tests lists and co

  • search_live_sources

    Return live, unchecked papers from Europe PMC. Use this for gaps in database coverage or an explicit live literature search. Use search_publications instead for stored papers, or search_findings for checked claims. Live results have a separate unchecked label.

  • get_record

    Return one full peptide, publication, finding or trial record by PEP-, PUB-, FND- or TRL- ID. A peptide slug, PMID or NCT number also works. Use this for known records or fields omitted from compact results. Use resolve_peptide instead for an unclear name, or search_publications

  • get_evidence_map

    Return checked finding counts for one peptide by outcome group, evidence class and direction, plus year, design and safety counts. Use this to inspect evidence coverage and gaps. Use search_findings instead for individual claims and source sentences, or compare_peptides for sever

  • compare_peptides

    Return identity, evidence counts, outcome groups and top findings for 2 to 5 peptides, plus shared outcome groups. Use this for a comparison in one call. Use get_peptide_brief instead for a detailed summary of one peptide. The result compares evidence without ranking peptides as

  • get_changes

    Return record change events in sequence order. Use this to synchronize data after since_seq, with 0 for full history. Without since_seq, the response gives the newest page. next_since_seq supplies the continuation position. Use get_freshness instead for source import times, or ge

  • replay_query

    Return a saved search at its original data_seq, with the first page and result_set_hash comparison. Use this to check whether a recorded query reproduces identical data. Use search_findings with as_of_seq instead for a new search at an earlier sequence, or get_record with as_of_s

  • get_freshness

    Return source import and extraction times from stored study results. Use this to inspect data freshness. Use get_changes instead for record events, or get_my_usage for caller quotas. lag_hours measures time since success, not upstream backlog. source_latest_known is not reported

  • get_my_usage

    Return the caller's plan, grants, quotas and usage in the current windows. Use this to inspect access limits and remaining allowances. Use get_freshness instead for source import times, or get_changes for record updates. This tool reports account access, not evidence coverage.

Common questions

Is PepBank Peptide Research MCP: BPC-157, Retatrutide and Tirzepatide Studies and… safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.5.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

PepBank Peptide Research MCP: BPC-157, Retatrutide and Tirzepatide Studies and Trials

Look up what studies found about more than 160 peptides, such as BPC-157, semaglutide and GHK-Cu. Each result links to its paper and says if it came from people, animals or cells.

PepBank MCP connects your AI to PepBank, a database of peptide research. Add it to Claude, ChatGPT, Cursor or another MCP app. Your AI can then find a peptide by name and read a summary of its evidence. It can also search study findings and clinical trials, and compare up to five peptides. Each finding links to the sentence in the paper that supports it and cites its PMID or DOI. Developer guide: pepbank.io/developers.

Questions to try

  • What do studies say about BPC-157 for tendon healing?
  • Are there clinical trials testing GHK-Cu?
  • Compare the evidence for semaglutide and tirzepatide.
  • What doses do people report for BPC-157, and what doses did studies use?
