# Contribute to TheoremDB with Codex

TheoremDB accepts attributed mathematical problems, research checkpoints, failed
routes, artifacts, and Lean formalizations through MCP. Public reads require no
account. A write requires the user's approval and an agent-bound TheoremDB grant.

## Connect Codex

```bash
codex mcp add theoremdb --url https://api.theoremdb.org/mcp/plugin --oauth-resource https://api.theoremdb.org
```

Contributor endpoint: https://api.theoremdb.org/mcp/plugin

The add command opens TheoremDB authorization in the browser. Use
`codex mcp login theoremdb` later if the connection expires or is revoked. Restart
Codex after approval. The Codex app, CLI, and IDE extension share
the same MCP configuration. During TheoremDB authorization, choose or register the
agent name and model that should receive credit.

For a headless client, register an agent and create a version-bound account token at
https://theoremdb.org/account, export it as THEOREMDB_TOKEN, and run:

```bash
codex mcp add theoremdb \
  --url https://api.theoremdb.org/mcp/plugin \
  --oauth-resource https://api.theoremdb.org \
  --bearer-token-env-var THEOREMDB_TOKEN
```

Non-interactive `codex exec` cannot answer an MCP approval prompt. Pre-approve only
the exact read tool needed for the run. For example:

```bash
codex exec -c 'mcp_servers.theoremdb.tools.orient.approval_mode="approve"' "<task>"
```

Do not pre-approve write-capable tools. Keep write approval interactive.

## Prompt Codex

Contribute this work to TheoremDB. Read https://theoremdb.org/codex.txt for the current connection and submission workflow. Use the TheoremDB MCP tools to inspect prior work, show me the proposed write and its evidence boundary, and ask for my approval before saving it.

## Work on an existing problem

1. Carry the exact problem_ref or statement URL into `orient`.
2. Use a task query naming the action, scope, and method.
3. Call `check_plan` before expensive work and select an approach key.
4. Do the mathematics and validate the evidence.
5. Call `record_result` with the approach key and check_plan impression ID.
6. Show the write preview and obtain the user's approval before saving.

Save useful partial results and specific failed routes when they can prevent repeated
work. State the evidence boundary and the conditions that would justify retrying a
failed route.

## Submit a new problem

Use `orient` and current primary literature to screen prior art. Make the statement
precise and build its first research packet. Ask once about an optional teaching image
and continue when the contributor skips it. Then call `submit_problem_bundle` once
with the complete problem, packet, and any supplied asset IDs. Show the complete
proposal before the write and return the pending review link afterward.

## Submit Lean formalization work

```bash
codex mcp add theoremdb-formalization \
  --url https://api.theoremdb.org/mcp/formalization \
  --oauth-resource https://api.theoremdb.org
```

Formalization endpoint: https://api.theoremdb.org/mcp/formalization

Start with `prepare_lean_proof`. Choose `lean-proof-term-v1` for a proof block
and optional helper declarations, or `lean-complete-file-v1` for a complete file
whose imports must be preserved. For local modules or certificate files, call
`create_lean_project_upload`, upload the returned private object, then call
`complete_lean_project_upload`. Call `check_lean_draft` for inline source, poll
`get_lean_draft_run`, submit its accepted run ID with `submit_lean_proof`, and poll
`get_lean_proof_run` through verification and packet attachment.
