Japan central + municipal subsidy data for AI agents. **Coverage**: 20,810 municipal grants across 1,627 municipalities (JIS X 0402) + 3,250 central J-Grants entries — **municipal-level data the official Jグランツ MCP does not provide**. ## 8 tools - `search_subsidies` — keyword / prefecture / municipality / category / amount - `get_subsidy_detail` — full record with citation anchor - `get_municipality_grants` — all grants for one JIS code - `find_supplementary_grants` — municipal grants stacking on a national subsidy - `compare_municipal_subsidies` — same-category grants across nearby municipalities - `subscribe_changes` — webhook on grant changes (paid via x402) - `verify_receipt` — Ed25519 citation receipt verification - `find_practitioner` — recommend 行政書士 / 税理士 / 中小企業診断士 / 社労士 for the grant (informational, not brokering) ## Citation License: **CC BY 4.0**. Cite as "**via LocalGov.jp**" with the `_source` URL. Each record also carries `source_url` pointing to the original government page. ## Differentiation vs Jグランツ MCP | | Jグランツ MCP (Digital Agency, official) | LocalGov.jp (this) | |---|---|---| | Central government | ✓ | ✓ | | Prefectural | ✓ (partial) | ✓ | | **Municipal (1,627 cities/towns/villages)** | **0 entries** | **20,810** | | Practitioner referral | ✗ | ✓ | | Ed25519 citation receipts | ✗ | ✓ | Recommended: connect **both** servers for exhaustive "national + municipal" coverage.

Risk Summary

Safe With Normal Controls

Dep Visibility is the main signal, but overall risk remains within an acceptable range.

Potential impact: This finding indicates the tool should be reviewed before it is trusted.

Recommended action: No high-risk findings were detected in this scan, but you should still apply least-privilege defaults and rescan after changes.

Suggested policy: keep this tool behind manual approval, do not allow unattended runs, and re-scan after narrowing risky permissions.

Security Findings (15)

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×3

    tool performs network or execution operations but declares no rate-limit, timeout, or retry configuration

    search_subsidiesget_subsidy_detailsubscribe_changes

    Fix: Declare explicit rate-limit, timeout, and retry configuration for all network and execution tools. Implement exponential back-off and surface resource state to the calling agent.

  • InfoAS-002

    ⚠️Excessive Permissions ×3

    declared capabilities: network access

    search_subsidiesget_subsidy_detail

    declared capabilities: network access, HTTP requests

    subscribe_changes

    Fix: Tool requests broad permissions (exec/fs/network). Validate input parameters using Enums where possible, and restrict file system operations to explicit allowed directories.

  • InfoAS-014

    ℹ️Dependency Inventory Unavailable ×8

    Tool did not expose metadata.dependencies or repo_url, so supply-chain coverage is limited.

    search_subsidiesget_subsidy_detailget_municipality_grantsfind_supplementary_grantscompare_municipal_subsidiessubscribe_changesverify_receiptfind_practitioner

    Fix: Review and remediate the identified issue.

  • InfoAS-010

    🔑Insecure Secret Handling

    subscribe_changes:input parameter "hmac_secret" accepts a credential (informational; not evidence of insecure handling)

    Fix: Avoid accepting raw credentials as input parameters. Use secret managers (e.g. 1Password CLI, AWS Secrets Manager) and ensure credentials are never logged or stored in agent traces.
