## Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.
This guide explains the easiest and most robust way to connect your Past.dev account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,500+ applications directly into their agent harness — including Hermes. It can:
- Search and load tools from relevant toolkits on-demand, reducing context usage.
- Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
- Manage app authentication end-to-end with zero manual overhead.

## Connect Past.dev to Hermes

### Integrating Past.dev with Hermes
### Using Composio Connect CLI
1. Install the Composio CLI
Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

```bash
curl -fsSL https://composio.dev/install | bash
```

## What is the Past.dev MCP server, and what's possible with it?

The Past.dev MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Past.dev account. It provides structured and secure access to durable, source-backed memory, identities, audiences, usage data, diagnostics, and request history, so your agent can store and recall memories, manage identity access, diagnose ingestion, and inspect or clean up memory on your behalf.
- Durable memory ingestion and recall: Have your agent store timestamped information, ingest memory in batches, and recall ranked, source-backed context for an identity.
- Identity and audience management: Let the agent create, update, list, or remove identities and organize access with fixed or trait-based audiences.
- Ingestion diagnostics: Direct your agent to estimate ingestion costs, check processing status, explain partial or failed ingestions, and retry eligible work.
- Usage and activity monitoring: Instruct your agent to review credit usage, inspect API request history, and analyze request counts over selected time periods.
- Memory lineage and cleanup: Have your agent trace how memories and source information relate over time, inspect timeline details, and permanently delete selected memory data when needed.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `PAST_DEV_BULK_REPLACE_IDENTITIES` | Replace Identities in Bulk | Atomically create or replace complete trait sets for up to 1,000 identities; omitted traits replace the identity with no traits. |
| `PAST_DEV_DELETE_AUDIENCE` | Delete Audience | DESTRUCTIVE ACCESS CHANGE: Permanently delete an audience. Its stored memory remains but becomes permanently unreachable. The default project audience cannot be deleted. |
| `PAST_DEV_DELETE_IDENTITY` | Delete Identity | DESTRUCTIVE: Permanently delete an identity directory record and remove it from every audience. Stored memory associated with the identity remains and is not deleted. |
| `PAST_DEV_DELETE_INGESTION_MEMORY` | Permanently Delete Ingestion Memory | DESTRUCTIVE: Permanently delete every data point accepted by one ingestion and memory depending only on those points. This cannot be undone; the ingestion status and audit record remains readable. |
| `PAST_DEV_DELETE_MEMORY_DATA_POINT` | Delete Memory Data Point | DESTRUCTIVE: Permanently delete one data point by its caller-owned source id and remove memory derived from it. This cannot be undone; the purge completes asynchronously. |
| `PAST_DEV_DELETE_MEMORY_DATA_POINTS` | Delete Memory Data Points | DESTRUCTIVE: Permanently and atomically delete up to 1,000 data points by caller-owned source id and remove memory derived from them. This cannot be undone; the purge completes asynchronously. |
| `PAST_DEV_ESTIMATE_INGESTION` | Estimate Ingestion | Cut files into data points, plan batches, and estimate credits without storing data or spending credits. |
| `PAST_DEV_EXPLAIN_INGESTION` | Explain Ingestion | Diagnose how far one send progressed, including per-item searchability, memory counts, failure details, and the recommended next step. |
| `PAST_DEV_FIND_TRACE_ROOTS` | Find Trace Roots | Find memory and source nodes for lineage or timeline inspection, returning independent memory and source cursors. |
| `PAST_DEV_GET_AUDIENCE` | Get Audience | Read one fixed, rule, or default audience with its definition and current membership and memory counts. |
| `PAST_DEV_GET_IDENTITY` | Get Identity | Return one identity's traits, origin, timestamps, and current audience memberships. |
| `PAST_DEV_GET_INGESTION_STATUS` | Get Ingestion Status | Poll one ingestion for processing, completion, failure, and project readiness without consuming metered request quota. |
| `PAST_DEV_GET_REQUEST` | Get API Request | Read one API call and its retained allowlisted headers and request/response payload; bearer credentials are never returned. |
| `PAST_DEV_GET_REQUEST_HISTOGRAM` | Get Request Histogram | Count accepted, failed-later, and rejected API calls in provider-selected time buckets using request-log filters. |
| `PAST_DEV_GET_TRACE_LINEAGE` | Get Trace Lineage | Read what a memory or source was built from and what was built on it, including graph edges and hidden-node count. |
| `PAST_DEV_GET_TRACE_NODE` | Get Trace Node | Read one memory or source node with revision, validity, replacement, request, content, and graph counts. |
| `PAST_DEV_GET_TRACE_TIMELINE` | Get Trace Timeline | Read rooted source and memory work, ingestions, recalls, and supersessions on a clock for a window of at most 31 days. |
| `PAST_DEV_GET_USAGE` | Get Usage | Return the current UTC month's credit balance, metering state, and project ingestion, recall, and cap usage. |
| `PAST_DEV_INGEST_MEMORY` | Ingest Memory | Ingest one timestamped data point into durable memory, optionally associating it with an identity and audience; reusing an id replaces the prior revision when stored fields change. |
| `PAST_DEV_INGEST_MEMORY_BATCH` | Ingest Memory Batch | Atomically ingest 1 to 1,000 ordered memory data points in one request, avoiding fragile per-item agent loops. |
| `PAST_DEV_LIST_AUDIENCES` | List Audiences | List every audience in the connected project, including the default project audience and current membership and memory counts. |
| `PAST_DEV_LIST_IDENTITIES` | List Identities | List project identities newest first, optionally filtering by one trait, and return a cursor for the next page. |
| `PAST_DEV_LIST_REQUESTS` | List API Requests | List the connected project's API calls newest first, with filters and a cursor for the next page. |
| `PAST_DEV_RECALL_MEMORY` | Recall Memory | Return ranked, source-backed memory visible to an identity for a query, with optional time range, sort order, and evidence budget controls. |
| `PAST_DEV_RECOMPUTE_AUDIENCE` | Recompute Audience | Recompute an audience's membership from its definition and apply the refreshed access set to recall immediately. |
| `PAST_DEV_REPLACE_AUDIENCE` | Create or Replace Audience | Create or completely replace a fixed-list or trait-rule audience and its access definition. The default project audience cannot be replaced. |

## Conclusion

### Way Forward
With Past.dev connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
- Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Past.dev MCP?

With a standalone Past.dev MCP server, the agents and LLMs can only access a fixed set of Past.dev tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Past.dev and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Past.dev tools.

### Can I manage the permissions and scopes for Past.dev while using Tool Router?

Yes, absolutely. You can configure which Past.dev scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Past.dev data and credentials are handled as safely as possible.
