How to connect Past.dev MCP with ChatGPT

ChatGPT can take action across your apps and files, stay with a project for hours, and turn a goal into finished materials like sheets, slides, and docs, not just answers.

In this guide, I will explain the easiest and most secure way to connect your Past.dev account to ChatGPT via Composio Connect, so it can store memories, recall source-backed context, inspect memory traces, manage identities, and clean up data through natural language commands without ever putting your account credentials at risk.

Why use Composio over default connectors?

  • Apps with read and write access. Default connectors mostly can read your data. Composio's Past.dev integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
  • 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand.
  • Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

Prerequisites

Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.

Step-by-step: Connect Past.dev to ChatGPT

1. Install the Composio plugin

3. Start using Composio

That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread Past.dev messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize Past.dev.

Option 2: Add Composio as an MCP server

If you cannot use the plugin marketplace, add Composio as a custom MCP server instead.

1. Open the MCP settings

In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.

2. Add the server

Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
ChatGPT Add server dialog with the name Composio, type Streamable HTTP, and the Composio MCP URL

Then click Save. The Composio server now appears in your MCP plugins list.

3. Authenticate

Click Authenticate on the Composio entry, log in via Composio, and click Allow access. Composio tools are then available in ChatGPT the same way as with the plugin.

What you can do after connecting Past.dev

  • Recall product decisions from last quarter
  • Inspect memory traces for recent requests
  • Clean up memories tied to old projects

Security + privacy notes (important)

  • Use least-privilege access: Only grant permissions you actually need.
  • Review OAuth permissions before approving: Make sure requested scopes match what you expect Composio and ChatGPT to do.
  • Keep write actions human-reviewed: For actions like sending messages, creating labels, or editing drafts, keep manual confirmation enabled.
  • Be careful with sensitive data: Avoid using this setup with highly sensitive information unless allowed by your personal, company, or client policies.
TOOLS

Supported Tools

Every Past.dev action and event your agent gets out of the box.

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.

Delete Audience

DESTRUCTIVE ACCESS CHANGE: Permanently delete an audience.

Delete Identity

DESTRUCTIVE: Permanently delete an identity directory record and remove it from every audience.

Permanently Delete Ingestion Memory

DESTRUCTIVE: Permanently delete every data point accepted by one ingestion and memory depending only on those points.

Delete Memory Data Point

DESTRUCTIVE: Permanently delete one data point by its caller-owned source id and remove memory derived from it.

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.

Estimate Ingestion

Cut files into data points, plan batches, and estimate credits without storing data or spending credits.

Explain Ingestion

Diagnose how far one send progressed, including per-item searchability, memory counts, failure details, and the recommended next step.

Find Trace Roots

Find memory and source nodes for lineage or timeline inspection, returning independent memory and source cursors.

Get Audience

Read one fixed, rule, or default audience with its definition and current membership and memory counts.

Get Identity

Return one identity's traits, origin, timestamps, and current audience memberships.

Get Ingestion Status

Poll one ingestion for processing, completion, failure, and project readiness without consuming metered request quota.

Get API Request

Read one API call and its retained allowlisted headers and request/response payload; bearer credentials are never returned.

Get Request Histogram

Count accepted, failed-later, and rejected API calls in provider-selected time buckets using request-log filters.

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.

Get Trace Node

Read one memory or source node with revision, validity, replacement, request, content, and graph counts.

Get Trace Timeline

Read rooted source and memory work, ingestions, recalls, and supersessions on a clock for a window of at most 31 days.

Get Usage

Return the current UTC month's credit balance, metering state, and project ingestion, recall, and cap usage.

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.

Ingest Memory Batch

Atomically ingest 1 to 1,000 ordered memory data points in one request, avoiding fragile per-item agent loops.

List Audiences

List every audience in the connected project, including the default project audience and current membership and memory counts.

List Identities

List project identities newest first, optionally filtering by one trait, and return a cursor for the next page.

List API Requests

List the connected project's API calls newest first, with filters and a cursor for the next page.

Recall Memory

Return ranked, source-backed memory visible to an identity for a query, with optional time range, sort order, and evidence budget controls.

Recompute Audience

Recompute an audience's membership from its definition and apply the refreshed access set to recall immediately.

Create or Replace Audience

Create or completely replace a fixed-list or trait-rule audience and its access definition.

Replace Identity

Create an identity or replace its complete trait set; omitted or empty traits remove all existing traits.

Retry Ingestion

Retry a stopped or failed ingestion under its existing id without spending additional credits; completed ingestions are rejected.

Update Identity Traits

Merge selected identity traits while preserving unspecified keys; set a trait value to null to remove that key.

FAQ

Frequently asked questions

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.

Yes, you can. ChatGPT 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.

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.

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.
