Capabilities & Tool Schemas (3)
Inspect callable tools, capabilities, and parameters exposed to AI agents by Agentseal MCP.
record_actionRecord an agent action to the audit trail. Call this after significant actions to create a cryptographically chained record of what happened and why.
query_actionsLook up previously recorded actions from the audit trail. Use this to check what actions have been taken or recall past decisions.
verify_chainVerify the integrity of the hash chain. Each entry's SHA-256 hash includes the previous entry's hash — if any record was modified, the chain breaks and this reports where.
Documentation Overview
agentseal-mcp
MCP server for AgentSeal. Tamper-proof audit logs for AI agents, using SHA-256 hash chains.
Every agent action is recorded in a hash chain. With this, you can actually prove to your clients that your agent did what it said it did.
Setup
Claude Desktop
Add to your claude_desktop_config.json:
Restart Claude Desktop after saving.
Cursor / Other MCP hosts
Same configuration — add the server with your API key.
Environment variables
| Variable | Required | Description |
|---|---|---|
AGENTSEAL_API_KEY | Yes | Your API key from agentseal.io |
AGENTSEAL_URL | No | Custom API base URL (defaults to production) |
Tools
record_action
Record an agent action to the audit trail. Call this after significant actions to create a cryptographically chained record of what happened and why.
| Parameter | Type | Required | Description |
|---|---|---|---|
agent_id | string | Yes | Identifier for the agent (e.g. research-bot) |
action_type | string | Yes | What kind of action (e.g. email:send, file:write, api:call) |
action_params | object | No | Details of the action |
reasoning | string | No | Why the agent decided to take this action |
authorized_by | string | No | Who or what approved the action |
Returns a sequence number and SHA-256 hash confirming the entry was chained.
query_actions
Look up previously recorded actions from the audit trail. Use this to check what actions have been taken or recall past decisions.
| Parameter | Type | Required | Description |
|---|---|---|---|
agent_id | string | No | Filter by agent |
action_type | string | No | Filter by action type |
limit | number | No | Max entries to return (default 20) |
verify_chain
Verify the integrity of the hash chain. Each entry's SHA-256 hash includes the previous entry's hash — if any record was modified, the chain breaks and this reports where.
| Parameter | Type | Required | Description |
|---|---|---|---|
agent_id | string | No | Verify chain for a specific agent. If omitted, verifies all entries. |
Returns the number of entries verified and whether the chain is intact.
How it works
Each recorded action is hashed with SHA-256. That hash includes the previous entry's hash, forming a chain. Modify any record and every hash after it changes — verify_chain catches it instantly.
