SAM.gov Opportunities

SAM.gov Opportunities MCP server

This MCP server lets an AI assistant (Claude Desktop, Cursor, VS Code, Claude Code or any other MCP client) search U.S. federal contract opportunities on SAM.gov: solicitations, sources sought, presolicitations and award notices.

Each call runs the Apify actor cleandatalabs/samgov-opportunities under your own Apify token. You don't need a SAM.gov API key and there is no 10-requests-per-day limit.

Not a developer? If you'd rather have a person watch a SAM.gov search for you, Clean Data Labs offers a free hand-checked sample: one search, the last 7 days, up to 10 notices.

Tools

Tool	What it does
search_opportunities	Searches active notices, newest first. Filters: keywords, naics_codes, psc_codes (both accept prefixes, e.g. 2362 or Z2), set_asides (SBA, 8A, HZC, SDVOSBC, WOSB, EDWOSB and others), agencies (by name), states (place of performance), notice_types, posted_since (YYYY-MM-DD, posted or updated on or after that date; default is the last 7 days), deadline_within_days, open_for_response_only, max_results (default 25, max 200) and detail (compact or full).
get_opportunity	Fetches one notice by notice ID, sam.gov/opp/... URL or solicitation number. A solicitation number returns all of its notices, including the award (winner, UEI, amount).
what_changed_since_last_check	Monitor mode: give a stable monitor_id plus the same filters each time and get only notices that are new or changed since the previous call, each with change_type (new, amended, deadline_changed, amount_changed, awarded, canceled, notice_type_changed, updated), changed_fields, plain-English change_summary, structured text_diff (title, description passages, attachments, deadline/amount/etc.) and previous values (previous_response_deadline, previous_award_amount_usd, previous_notice_id). Unchanged notices are free. The first call defaults to a free baseline.

Compact rows include the notice ID, title, solicitation number, type, department, agency and office, posted and deadline dates, NAICS, PSC, set-aside, place of performance, primary contact, attachment count, award fields (amount, date, awardee name, UEI, CAGE, award number), monitor change fields (change_type, changed_fields, change_summary, text_diff, previous values), optional attachment_archive / attachments_archived when the actor archived files, and the SAM.gov link. detail: "full" adds the description, all contacts and attachment links.

search_opportunities and get_opportunity are read-only. what_changed_since_last_check stores its memory (a samgov-monitor-state key-value record) in your own Apify account.

Cost

The actor charges $0.003 per returned notice (25 results cost $0.075), billed to the Apify account that owns the token. Apify's free plan includes $5 of monthly credit. Each tool call carries a spending cap: the lower of max_results × $0.003 and SAMGOV_MAX_CHARGE_USD (default $0.30). Each result reports estimated_cost_usd.

Install

You need uv (for uvx), or Python 3.10+ with pip, and an Apify API token from Console > Settings > API & Integrations.

Claude Desktop / Cursor / any client with an mcpServers config

{
  "mcpServers": {
    "samgov": {
      "command": "uvx",
      "args": ["samgov-opportunities-mcp"],
      "env": { "APIFY_TOKEN": "apify_api_..." }
    }
  }
}

Claude Code

claude mcp add samgov --env APIFY_TOKEN=apify_api_... -- uvx samgov-opportunities-mcp

VS Code (.vscode/mcp.json)

{
  "inputs": [{ "type": "promptString", "id": "apify-token", "description": "Apify API token", "password": true }],
  "servers": {
    "samgov": { "type": "stdio", "command": "uvx", "args": ["samgov-opportunities-mcp"],
                "env": { "APIFY_TOKEN": "${input:apify-token}" } }
  }
}

From source

git clone https://github.com/clean-data-labs-org/samgov-opportunities-mcp && cd samgov-opportunities-mcp
pip install -e .
APIFY_TOKEN=apify_api_... samgov-opportunities-mcp   # speaks MCP over stdio

Configuration

Env var	Default	Meaning
APIFY_TOKEN	(required)	Your Apify API token. Runs are billed to this account.
SAMGOV_MAX_CHARGE_USD	0.30	Spending cap per tool call.
SAMGOV_ACTOR_BUILD	latest	Actor build tag or number to run. latest is actor 0.3.7 (monitor change_summary/text_diff, opt-in downloadAttachments → attachment_archive). Leave unset so the default latest is used. get_opportunity needs 0.3+, what_changed_since_last_check needs 0.3.4+.

Actor 0.3.7 (on latest): monitor rows include change_summary and text_diff, and every row carries set_aside / set_aside_description. Attachment archiving is opt-in on the actor via downloadAttachments: true (files land in a persistent KV store with sha256 dedupe; rows get attachment_archive[] / attachments_archived). This MCP package does not yet expose a download_attachments tool flag; set it only if you call the actor directly.

Example prompts

• "Find small-business set-aside janitorial contracts in Colorado posted this week."
• "Any VA construction solicitations under NAICS 2362 due in the next 30 days?"
• "Who won solicitation FA813226Q0061, and for how much?"
• "What changed since last check in my construction-co watch (NAICS 236220, Colorado)?"
• "Show me HUBZone IT services opportunities (NAICS 5415) from the Army since 2026-11-01."

No-install alternative: Apify's hosted MCP server

To skip installing anything, point your client at Apify's hosted server and limit it to this actor:

{ "mcpServers": { "samgov": { "url": "https://mcp.apify.com/?tools=cleandatalabs/samgov-opportunities" } } }

It signs you in with OAuth, or you can send Authorization: Bearer <APIFY_TOKEN>. It exposes the actor as one generic tool with every raw actor input, plus run and dataset helper tools. This package instead offers three focused tools with typed filters, compact output and a per-call spending cap.
