ChemCP vs Mhra Uk
A side-by-side look at the ChemCP and Mhra Uk MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose ChemCP for biology & bioinformatics work as a local process; choose Mhra Uk for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

Mhra Uk tools 4
mhra_searchSearch the UK MHRA products register by product name, brand name or active substance — e.g. "ibuprofen", "Nurofen", "atorvastatin". Post-Brexit the EMA register does not cover the UK, so this is the UK authorisation surface. Returns one row per DOCUMENT (a product usually has an SmPC, a patient leaflet and sometimes an assessment report), each with its PL number, the MHRA territory it covers, the document date and a direct link to the authoritative PDF. Use mhra_product to gather every document for one PL number.mhra_productEvery MHRA document held for one UK licence number, grouped by document type — the SmPC that carries the authorised indications, the patient leaflet, and the public assessment report where one exists. Accepts any spelling of the PL number ("PL 29831/0798", "PL29831/0798", "PL298310798", and the PLGB / PLNI forms). Returns the authoritative PDF URL for each. The indication text itself lives inside the SmPC PDF, not in this register, so this tool gives you the exact document to read rather than a summary of it.mhra_recent_changesMHRA documents added or revised since a date, newest first — the weekly-refresh feed. Pass an ISO date such as "2026-09-01". Returns the same rows as mhra_search plus the cutoff that was applied, so replaying the same `since` gives the same answer. NOTE what the register can and cannot tell you: a new or revised DOCUMENT is what is recorded here. A withdrawal is not published as an event, so this cannot report withdrawals — treat it as "new and changed", not "new, changed and withdrawn".mhra_snapshotHow big the UK register currently is and how to walk all of it: total document count, the count per document type, the newest document date, and the paging recipe for a full enumeration. MHRA publishes no bulk download, so this returns the enumeration path rather than a file URL — and it returns those counts, never the documents themselves.

Frequently asked questions
ChemCP is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Mhra Uk belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick ChemCP for biology & bioinformatics work and Mhra Uk for biology & bioinformatics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
ChemCP has no declared pricing — check the project's own site. Mhra Uk has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add chemcp and mhra-uk as separate keys in the same mcpServers object, and your assistant will call tools from either one.
