Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

HTTP Network Access

Connects to external APIs or services over the internet.

env_vars

Applies to the server that hosts this plugin, not to your machine.

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Add this to your MCP configuration to connect:

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.

Server address

https://pepbank.io/mcp

Transport: Streamable HTTP. The server runs at this address. This repository holds its listing files. The server code is not in it.

Add it to your AI app

Claude: open Customize, then Connectors. Select Add custom connector. Name it PepBank and enter https://pepbank.io/mcp.

ChatGPT: turn on Developer mode in Settings, under Security and login. Open Plugins and select +, then Add custom MCP server. Name it PepBank and enter https://pepbank.io/mcp.

Grok: open grok.com/connectors. Select New Connector, then Custom. Enter https://pepbank.io/mcp.

Claude Code:

claude mcp add --transport http pepbank https://pepbank.io/mcp

Codex (config.toml):

[mcp_servers.pepbank]
url = "https://pepbank.io/mcp"

Cursor (~/.cursor/mcp.json):

{ "mcpServers": { "pepbank": { "url": "https://pepbank.io/mcp" } } }

VS Code (.vscode/mcp.json):

{ "servers": { "pepbank": { "type": "http", "url": "https://pepbank.io/mcp" } } }

Gemini CLI (settings.json):

{ "mcpServers": { "pepbank": { "httpUrl": "https://pepbank.io/mcp" } } }

Other apps: add https://pepbank.io/mcp as a remote server with Streamable HTTP.

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:

npx skills add pepbank/peptide-research-mcp

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?
