AI agents call search_open_grants to retrieve information from Foundation Discovery without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search_open_grants only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Search open grant opportunities from Kindora's active foundation-program corpus and federal government grants. Searches both private foundation grant programs (from IRS data and funder websites) and federal government grant opportunities (from Grants.gov). Uses full-text search with natural language understanding — queries are parsed into individual terms with stemming, so "youth after school programs" matches programs about youth, after-school, and programming even if those exact words don't appear together. Search covers program names, descriptions, focus areas, beneficiary types, and geographic focus fields. Use the state parameter to focus on geographically relevant opportunities. Query syntax: - Natural language: "affordable housing for seniors" (matches any of these terms) - Quoted phrases: '"after school"' (matches exact phrase) - Exclusion: "education -higher" (matches education, excludes higher education) - Combine: '"mental health" youth -adult' (phrase + term + exclusion) - No query: returns broadly open programs sorted by upcoming deadlines (browsing mode) Args: query: Natural language search query. Searches across program names, descriptions, focus areas, beneficiary types, and geographic focus. Supports quoted phrases for exact matching and -term for exclusion. Example: "youth outdoor education", "affordable housing", "STEM education for girls", "food bank hunger", "climate change environment", "domestic violence women" focus_area: Filter foundation programs by focus area (matches values in focus_areas array). Example: "Education", "Health", "Environment" agency: Filter government grants by agency name (case-insensitive). Example: "Department of Education", "NSF", "NIH" state: Two-letter US state code to filter by geographic relevance. Returns programs focused on that state plus nationally available programs. Example: "CA", "NY", "TX" country: Country name for non-US geographic filtering. Returns programs whose geographic_focus is tagged for that country plus any tagged Global / International / Worldwide. Use this instead of state for international queries — passing "India" via state would error because state requires a US code. Mixing state with a non-US country is rejected. Example: "India", "Kenya", "Mexico", "Global" deadline_days: How far ahead to search for deadlines, in days. Default: 90 (3 months). Maximum: 365 (1 year). Rolling/always-open programs are always included regardless. min_award: Minimum grant size filter in dollars. Example: 50000 (grants of $50K+) max_award: Maximum grant size filter in dollars. Example: 500000 (grants up to $500K) nonprofit_only: Only show nonprofit-eligible government grants. Default: True source: Filter by grant source type. Options: "foundation" (private foundation programs only), "government" (federal grants only), or omit for both sources combined. PREFER omitting this — the foundation corpus is much larger, and filtering to government-only often returns few or zero results. limit: Maximum number of results to return. Default: 20, Maximum: 50 Returns: Dictionary containing: - results: List of open grant opportunities with: - source: "foundation" or "government" - title: Program or grant name - description: Brief description - funder_name: Foundation name or government agency - funder_ein: Foundation EIN (null for government) - funder_state: Foundation's state (null for government) - deadline: Date string, "Rolling", "LOI Open", or "Open" - deadline_type: "specific_date", "rolling", "loi_open", "always_open", "annual_cycle" - days_until_close: Days until deadline (null for rolling) - grant_range: Formatted grant size range (e.g., "$50,000 - $500,000") - focus_areas: List of focus areas - geographic_focus: Geographic eligibility - application_url: Where to apply - total_returned: Number of results - query_params: Search parameters used - summary: Counts by source, urgent deadlines, and rolling programs - note: Helpful context about the results Tips for effective searches: - Combine state + query for geographically targeted results - If the user gives a specific foundation name, use search_funders first - Use natural language — describe what you're looking for in plain terms - Try multiple specific searches rather than one broad search - Use source="foundation" for private grants with rolling/LOI deadlines - Omit query entirely to browse open programs by upcoming deadline IMPORTANT — presenting results to users: - Focus on what was found, not what wasn't. Present results positively. - Do NOT comment on corpus size, data limitations, or coverage gaps. - If few results are returned, suggest trying related keywords or using search_funders to find aligned foundations — many accept unsolicited inquiries or run annual grant cycles that may not have an open window right now. Frame this as "here are additional prospects to explore" not "the search didn't find enough." - Many excellent funders don't post public open calls — they fund through relationships, LOIs, and nominations. Use search_funders and get_funder_profile to identify these funders as proactive prospects. Examples: search_open_grants(query="youth outdoor education", state="CA") search_open_grants(query="affordable housing", state="NY", source="foundation") search_open_grants(query="STEM education for girls", state="TX") search_open_grants(query="food bank hunger", min_award=10000) search_open_grants(query="mental health services", state="CA") search_open_grants(query="climate change environment", source="foundation") search_open_grants(source="government", nonprofit_only=True, state="NY") search_open_grants(focus_area="Environment", source="foundation") search_open_grants(query="community health workers", country="India") search_open_grants(query="climate resilience", country="Global") search_open_grants() # Browse open programs by upcoming deadline Related tools: - search_funders: Find grantmaking organizations by name or location — use this alongside search_open_grants to identify foundations that may be a good fit even if they don't have a posted open grant right now - get_funder_profile: Get detailed profile for a specific foundation - get_foundation_grants: See past grants made by a foundation. It is categorised as a Read tool in the Foundation Discovery MCP Server, which means it retrieves data without modifying state.
Register the Foundation Discovery MCP server in PolicyLayer and add a rule for search_open_grants: 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 Foundation Discovery. Nothing to install.
search_open_grants 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 search_open_grants 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 search_open_grants. 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.
search_open_grants is provided by the Foundation Discovery MCP server (https://kindora-mcp.azurewebsites.net/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
