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

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

Look up what studies found about BPC-157, retatrutide, tirzepatide, GHK-Cu, TB-500 and 160+ other peptides. 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.

Command line and local server (npm)

The pepbank package runs the same server over stdio for apps that need a local server, and answers from the terminal:

npx pepbank brief BPC-157
npx pepbank search tendon healing
npx pepbank trials GHK-Cu

Local server config for MCP apps:

{ "mcpServers": { "pepbank": { "command": "npx", "args": ["-y", "pepbank"] } } }

Tools

Tool	What it does
resolve_peptide	Finds the peptide that a name, alias or code means
get_peptide_brief	Reads the evidence summary for one peptide, with key findings, trials, studied doses and approval status
get_community_practice	Reads what community sources report about how people use one peptide: uses, doses, side effects and cautions, each with its sources. Trials did not test these reports
search_peptides	Lists peptides and filters them by name, category or evidence level
search_findings	Searches study findings, with the source sentence and the PMID or DOI for each
search_publications	Finds papers and shows which ones have checked findings
search_trials	Finds registered clinical trials, with status, phase and posted results. The list view shows up to 100 trials per page
search_live_sources	Searches Europe PMC for papers that PepBank does not cover yet. These results are not checked
get_record	Reads one full peptide, paper, finding or trial record
get_evidence_map	Counts the findings for one peptide by outcome, evidence class and direction
compare_peptides	Compares the evidence for 2 to 5 peptides
get_changes	Lists data changes since a data version
replay_query	Runs a saved search again on the data version it first used
get_freshness	Shows when each source was last imported
get_my_usage	Shows your daily limits and how much of them you used

Prompts and resources

Name	Type	What it does
evidence_summary	Prompt	Summarizes the evidence for one peptide, with sources and coverage limits
compare_evidence	Prompt	Compares the evidence for 2 to 5 peptides
pepbank://guide	Resource	Explains evidence classes, coverage, data versions, citations and limits

Plugin package

This repository is also a plugin package that connects the server and adds one skill, skills/pepbank-peptide-research/SKILL.md.

• plugin.json and mcp.json: Agent Plugins format (Hermes)
• .claude-plugin/plugin.json and .mcp.json: Claude Code plugin format
• .cursor-plugin/plugin.json: Cursor plugin format
• openclaw.plugin.json: OpenClaw (ClawHub)

Install the skill with the skills CLI:

Questions to try

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

Peptide pages on PepBank

Each peptide has its own page with its studies, trials and approval status. For example: BPC-157, retatrutide, tirzepatide, GHK-Cu and TB-500.
