STRING MCP server
17 tools · Last check that passed 27 Oct 2026, 01:50 UTC
STRING's own remote MCP server gives an agent protein lookups, interaction networks, functional enrichment and annotation, and homology search from the STRING database, with no sign-in. Once a day, Stackduke connects to it the way any MCP client would, with no account and no sign-in, and lists its tools. It never runs them.

The tools the server listed at the last check that passed, at its default address and settings, with no sign-in; an account that signs in, or other settings, may see other tools. What a tool is counted as doing is Stackduke's cautious reading of the server's labels, the tool's name and its description: where they disagree it takes whichever says the tool can do most, so it overcounts on purpose. It does not say the server is safe, and it does not list what a tool cannot do. Descriptions are not shown, because they are written for models and may try to steer them.

One email when STRING's official MCP server adds, removes or changes tools, with what changed. Nothing else.
What to watch for
- STRING says the server is still under testing and development, so parts of how it works may change. STRING's MCP server help
- For its chat built on this server, STRING warns that AI answers may mix STRING results with other knowledge, and advises asking for STRING links to check them. STRING's MCP server help
How to limit it
With STRING's own settings, as its documentation describes them. Stackduke has not tested them.
- STRING recommends its standard API, not the MCP server, for work that is not driven by AI, and its download page for complete datasets. STRING's MCP server help
What Stackduke is designed to do
Stackduke is designed to sit between your agents and their MCP servers: to check each tool call against your rules before it runs, hold the risky ones for a person to approve, and keep a record of what was decided.
It does not yet forward or block tool calls for customers. Today it reads what this server offers and publishes what changes.
