# mygene.genes.info

Retrieve comprehensive annotation data for a single gene by its NCBI Entrez Gene ID or Ensembl gene ID. Returns the full gene record including: official symbol and name, gene type (protein-coding, ncRNA, pseudo, etc.), species taxon, gene summary, Ensembl transcript and protein IDs, UniProt Swiss-Prot accession, gene aliases, genomic coordinates (chromosome, start, end, strand), KEGG and Reactome pathway memberships, and Gene Ontology (GO) annotations across biological process, cellular component, and molecular function. Use mygene.genes.search or mygene.genes.symbol to discover Entrez Gene IDs first.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `fields` | string | no | Comma-separated fields to return. Default includes: symbol, name, taxid, entrezgene, type_of_gene, summary, ensembl, uniprot, alias, genomic_pos, pathway. Use " |
| `gene_id` | string | yes | Gene identifier — NCBI Entrez Gene ID (e.g. "1017" for CDK2, "672" for BRCA1) or Ensembl gene ID (e.g. "ENSG00000123374"). Obtain Entrez Gene IDs from mygene.se |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "mygene.genes.info",
    "arguments": {
      "gene_id": "<gene_id>"
    }
  }
}
```

## Why mygene.genes.info is rated Low

Tool only retrieves and returns gene annotation data with no side effects.

From the tool's own definition: "Retrieve comprehensive annotation data for a single gene"

## Use case

AI agents call mygene.genes.info to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mygene.genes.info": {}
  }
}
```
