Connect Talindrew to Codex
Talindrew's MCP server gives Codex a molecular biology toolkit: plasmid maps, restriction digests and gels, primer and CRISPR design, PubMed search, your saved sequences and lab notebook, and structure prediction. The Codex CLI, the IDE extension and the ChatGPT desktop app share one config, so adding it once covers all three.
Server URL
https://mcp.talindrew.com/mcpAuthentication: OAuth in your browser (CIMD or dynamic registration, chosen automatically).
Set it up
- Run the two commands below; the login opens Talindrew in your browser.
- Sign in with Google and click Allow.
- Start Codex and ask it to use Talindrew.
Terminal
codex mcp add talindrew --url https://mcp.talindrew.com/mcp
codex mcp login talindrew~/.codex/config.toml
[mcp_servers.talindrew]
url = "https://mcp.talindrew.com/mcp"Or let Codex set it up
Paste this into Codex; it adds Talindrew for you and checks the connection.
Add the Talindrew MCP server to Codex: run `codex mcp add talindrew --url https://mcp.talindrew.com/mcp` and then `codex mcp login talindrew` (it opens my browser to sign in). After I've approved it, call Talindrew's primer_tm tool on CGTTGTAAAACGACGGCCAGTGAAT.First things to ask
Use Talindrew to find the restriction sites in pUC19 and show me the map.With Talindrew, design PCR primers for bases 100-600 of this sequence: <paste DNA>Ask Talindrew for the melting temperature of CGTTGTAAAACGACGGCCAGTGAAT.Search PubMed with Talindrew for recent Golden Gate assembly protocols.
Other ways to connect
- Read-only connection: codex mcp login talindrew --scopes talindrew:read.
- Desktop app: Settings → MCP servers → Add server → Streamable HTTP → paste the URL → Save → Restart → Authenticate.
- IDE extension: gear menu → MCP servers → Add server, then Restart extension → Authenticate.
Remove or sign in again
codex mcp remove talindrew. To sign in again: codex mcp logout talindrew, then codex mcp login talindrew.
You can also disconnect any app from Talindrew itself under Settings → Connected apps.

Frequently asked questions
Yes. Talindrew is a remote MCP server at https://mcp.talindrew.com/mcp. Codex connects to it over Streamable HTTP and signs in with OAuth; OAuth in your browser (CIMD or dynamic registration, chosen automatically).
Codex shows Talindrew's results as text and data rather than interactive panels. Every result includes a link that opens it in the Talindrew app with the map, gel or tool ready.
Yes, to start. Connecting is free, and the sequence analysis, primer, CRISPR, literature and lab-notebook tools include 25 calls a week on the free plan; Plus ($9 a month, 7-day free trial) makes them unlimited. Structure prediction and FoldRx drug-discovery runs use the monthly allowance of a Pro or Max plan, exactly as in the app.
Try: "Use Talindrew to find the restriction sites in pUC19 and show me the map." or "Ask Talindrew for the melting temperature of CGTTGTAAAACGACGGCCAGTGAAT." Talindrew has 90 tools covering sequence analysis, digests and gels, primers, CRISPR guides, protein properties, cloning reactions in a workspace, PubMed and Europe PMC, NCBI Gene, Addgene, your saved sequences and notebook, and structure prediction.
