Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
FRED economic data: GDP, inflation, unemployment, rates, and 800k+ Federal Reserve time series.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

U.S. and global economic data for Claude Desktop and any MCP-compatible client, powered by FRED (Federal Reserve Economic Data). Search and pull from 800,000+ economic time series — GDP, inflation, unemployment, interest rates, and more — all from natural language.
npm package:
fred-economic-mcp· GitHub repo:danishashko/fred-economic-mcp.
Every tool returns human-readable markdown by default, or structured JSON on request (response_format: "json"). The server is lightweight (Python standard library + mcp only), applies FRED's transformations server-side so the AI gets clean numbers, and retries automatically when FRED rate-limits.
FRED requires a free API key. It takes about a minute:
FRED_API_KEY environment variable (see config below).Add this to your Claude Desktop config and restart Claude:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json{
"mcpServers": { "fred": { "command": "npx", "args": ["-y", "fred-economic-mcp"], "env": { "FRED_API_KEY": "your_free_fred_api_key_here" } } } }
On first launch the npx wrapper creates an isolated Python environment and installs the dependencies for you (a one-time step that can take a minute). You only need Python 3.10+ and Node.js 16+ on your machine.
npm install -g fred-economic-mcp
{
"mcpServers": { "fred": { "command": "fred-economic-mcp", "env": { "FRED_API_KEY": "your_free_fred_api_key_here" } } } }
| Tool | What it returns | Parameters |
|---|---|---|
search_series | Series matching a keyword, ranked by popularity (ID, title, units, frequency) | query, limit |
get_series_observations | The actual data values, with transforms and frequency aggregation | series_id, observation_start, observation_end, units, frequency, sort_order, limit |
get_series_info | Metadata for a series (units, frequency, seasonal adjustment, coverage, notes) | series_id |
get_economic_snapshot | Latest value of key U.S. indicators in one dashboard | *(none)* |
browse_category | Child categories and popular series within a FRED category | category_id |
get_releases | Economic data releases FRED tracks | limit |
Every tool also accepts response_format ("markdown", the default, or "json").
`get_series_observations` transforms (`units`): lin levels · chg change · ch1 change from year ago · pch percent change · pc1 percent change from year ago · pca compounded annual rate · log natural log.
Frequency aggregation (`frequency`): empty (native) · d daily · w weekly · m monthly · q quarterly · a annual.
You don't need to memorize IDs — search_series finds them — but these come up often:
| Series ID | Indicator |
|---|---|
GDPC1 | Real Gross Domestic Product |
UNRATE | Unemployment Rate |
CPIAUCSL | Consumer Price Index (CPI) |
PCEPI | PCE Price Index (the Fed's preferred inflation gauge) |
FEDFUNDS | Federal Funds Rate |
DGS10 | 10-Year Treasury Yield |
T10Y2Y | 10-Year minus 2-Year Treasury Spread |
PAYEMS | Nonfarm Payrolls |
MORTGAGE30US | 30-Year Fixed Mortgage Rate |
UMCSENT | Consumer Sentiment (University of Michigan) |
Once the server is connected, just ask Claude:
Asking *"What's year-over-year CPI inflation for the last few months?"* runs get_series_observations with series_id=CPIAUCSL, units=pc1:
# Consumer Price Index for All Urban Consumers: All Items (CPIAUCSL)
Units: Percent change from year ago · Frequency: m Total observations: 940
Latest: 3.39 (2026-04-01)
| Date | Value |
|---|---|
| 2026-04-01 | 3.39 |
| 2026-03-01 | 3.29 |
| 2026-02-01 | 2.43 |
"No FRED API key configured" Set FRED_API_KEY in your MCP client config (see Quick Start) to a free key from fredaccount.stlouisfed.org/apikeys, then restart the client.
"Command not found" / "Python not found" Make sure Python 3.10+ and Node.js 16+ are installed and on your PATH. On macOS/Linux, try python3.
"FRED is rate-limiting requests" FRED allows 120 requests/minute per key. The server retries automatically; if you still hit it, wait a minute.
Tools not showing up in Claude
FRED_API_KEY is set in the server's env block."FRED rejected the request" The series ID is probably wrong. Use search_series to find the correct ID, or get_series_info to confirm a series exists.
Using a different model or provider (LiteLLM, OpenRouter, NVIDIA NIM, a local model) This server never talks to a model. Your client starts it as a local process and speaks JSON-RPC over stdin/stdout, so changing ANTHROPIC_BASE_URL or swapping the model behind your client has no effect on it. If tools stop firing after a switch like that, check two things: the model has to support function calling, and a proxy configured to drop unsupported parameters can silently strip your tool definitions, which produces no error at all. Run /mcp in your client (or claude mcp list) to confirm the server is connected before suspecting the server.
If you would rather run the Python file directly instead of via npx:
1. Download the server and install the dependency
Save fred_mcp.py somewhere on your machine, then:
pip install mcp
(or pip3 on macOS/Linux)
2. Point Claude Desktop at it
{
"mcpServers": { "fred": { "command": "python3", "args": ["/absolute/path/to/fred_mcp.py"], "env": { "FRED_API_KEY": "your_key_here" } } } }
On Windows use "command": "python" and a path like "C:\\path\\to\\fred_mcp.py" (double backslashes or forward slashes).
3. Restart Claude Desktop.
429.unrate works..; those are shown as N/A.units transforms (e.g. pc1 for year-over-year %) are computed by FRED, so the values are authoritative — no client-side math.get_series_info to check before pulling a range.See CHANGELOG.md for the full version history.
