mygene.genes.symbol
Find a gene by its official gene symbol with an exact match for a specific species. Returns a single best-matching gene with full annotation: NCBI Entrez Gene ID, Ensembl gene ID, gene name, type, taxon, summary, UniProt accession, genomic coordinates, pathway memberships, and GO terms.

What mygene.genes.symbol does on Apibase
AI agents call mygene.genes.symbol 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
fields | string | — | Comma-separated fields to include in the response. Default includes: symbol, name, taxid, entrezgene, type_of_gene, summary, ensembl, uniprot, alias, genomic_po |
symbol | string | Yes | Official HGNC gene symbol (for human) or equivalent gene symbol in the target species. Case-insensitive (e.g. "BRCA1", "TP53", "EGFR", "KRAS"). Performs an exac |
species | string | — | Target species for the symbol lookup. Common values: "human", "mouse", "rat", "fruitfly", "zebrafish", "chicken", "pig", "dog". Can also use NCBI taxid (e.g. "9 |

Why mygene.genes.symbol is rated Low
Tool retrieves gene annotation data with no side effects or modifications.
From the tool's definition Find a gene by its official gene symbol, returns annotation data
Attacks that exploit this kind of access
The rule that runs mygene.genes.symbol safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mygene.genes.symbol, this is the rule to start with:
mygene.genes.symbol is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every mygene.genes.symbol call is checked against it from then on.
Questions about mygene.genes.symbol
Find a gene by its official gene symbol with an exact match for a specific species. Returns a single best-matching gene with full annotation: NCBI Entrez Gene ID, Ensembl gene ID, gene name, type, taxon, summary, UniProt accession, genomic coordinates, pathway memberships, and GO terms. Faster and more precise than full-text search when the official symbol is known. Case-insensitive (BRCA1, brca1, Brca1 all match). For human genes, use HGNC symbols (e.g. "TP53", "EGFR", "KRAS", "VEGFA"). Results can be used directly with mygene.genes.batch for comparative multi-gene analysis. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
mygene.genes.symbol accepts 3 parameters: fields, symbol, species. Required: symbol. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for mygene.genes.symbol: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.
mygene.genes.symbol is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mygene.genes.symbol rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mygene.genes.symbol. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mygene.genes.symbol is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
