Eco Policy MCP
Indian finance MCP server: mutual-fund NAVs, GST & income-tax tools, RBI rates, NSE quotes.
Runs on your machine from its package; the steps are below.
What it does
- Reads
- Writes
- High impact
At most: only reads or looks up information.
What it costs
FreeOdel charges nothing per call. The publisher may charge for its own service.
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
uvx eco-policy-mcp
MCP client config
{
"mcpServers": {
"eco-policy-mcp": {
"command": "uvx",
"args": [
"eco-policy-mcp"
]
}
}
}
An MCP server for Indian finance data — mutual-fund NAVs, GST & income-tax calculators, RBI policy rates and NSE market data — built for any MCP client (Claude, Cursor, Gemini CLI, VS Code, Cline, custom agents...), not just one.
Every successful response carries a provenance block (source, as_of,
reference), so AI agents can cite where each number came from instead of
hallucinating it.

Data sources & disclaimers
- AMFI (
NAVAll.txt) — official daily NAV dump; parsed and cached 6h. - mfapi.in — community mirror of AMFI's NAV archive (history, returns, SIP).
- RBI — curated policy-rate snapshot stamped with its as-of date; verify at rbi.org.in before acting on it.
- NSE — unofficial public endpoints; quotes may be delayed and endpoints can change without notice. Failures return structured errors, never raw HTML.
- Tax computations are estimators (excludes surcharge, capital-gains special rates); nothing here is investment or tax advice.
Configuration
All settings via env vars (prefix ECO_): ECO_TTL_AMFI_INDEX,
ECO_TTL_NSE_QUOTE, ECO_NSE_MIN_INTERVAL, ECO_HTTP_TIMEOUT,
