Download a gzip-compressed OEIS data file. Available files include: names.gz, stripped.gz, authors.gz, comments.gz, formulas.gz, keywords.gz, offsets.gz, programs.gz, or b-files (b{xxxxxx}.txt.gz where {xxxxxx} is a 6-digit sequence number).
AI agents call download_oeis_data_file to retrieve information from LODA API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves static, publicly available mathematical sequence data from OEIS. There are no side effects, no data creation or modification, no code execution triggered by the download itself, and no destructive operations. It is a straightforward read/fetch operation with minimal risk. The blast radius of misuse is negligible—an agent could retrieve large datasets but cannot alter or damage anything.
From the tool's definition Tool downloads pre-generated OEIS data files (names.gz, stripped.gz, authors.gz, comments.gz, formulas.gz, keywords.gz, offsets.gz, programs.gz, b-files).

Download a gzip-compressed OEIS data file. Available files include: names.gz, stripped.gz, authors.gz, comments.gz, formulas.gz, keywords.gz, offsets.gz, programs.gz, or b-files (b{xxxxxx}.txt.gz where {xxxxxx} is a 6-digit sequence number). It is categorised as a Read tool in the LODA API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the LODA API MCP Server MCP server in PolicyLayer and add a rule for download_oeis_data_file: 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 LODA API MCP Server. Nothing to install.
download_oeis_data_file 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 download_oeis_data_file 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 download_oeis_data_file. 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.
download_oeis_data_file is provided by the LODA API MCP Server MCP server (loda-lang/loda-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
